GEAR GUIDE: 2011-2012   Double Driver Sled Not just for tour companies anymore! Adanac is making several styles of double driver sleds. There are great reasons for owning one of these sleds in addition to your racing sleds or “tour” sleds. If you are a musher with friends that always want to go for a “ride”—try one of these sleds. You don’t have to pack the friend in your sled bag and they can get the experience of dog mushing. We make double drivers where two people can stand up in tandem. They each have their own upright stanchions, handlebar, double claw brake system, footboards, and drag mat (if desired). These sleds are great for training and great for tour operators. They are built to last using hand-picked ash and polyethylene plastics.

Arctic Oven Tent – The ultimate cold weather camping tent!  With its condensation-free interior and the option of putting a stove inside for warmth, this tent provides a sanctuary from harsh winter conditions.  The proven design of the Arctic Oven tent creates a warm and dry interior, allowing your gear to dry while you are comfortably asleep.  Steep side walls provide ample head and shoulder room while useable interior space is maximized with open floor designs, convenient storage pockets and utility loops.  With 12 models available, we are sure to have your dream tent!  These tents are designed and hand crafted by Alaska Tent & Tarp.   

Kick sleds A great way to get a smaller team out! We are also making kick sleds in addition to our full line of sprint, racing, distance, freight and kit sleds. Our kick sleds are lightweight, durable and made from hand-picked ash and poly. They come with a drag mat and are great for one-two dogs. Our version is modified from the Norwegian kick sleds. Hook up your dogs and start “kicking” down the trail. They can be made to fold down (if desired).

Arctic Oven Pipeline Tent The Arctic Oven tent line continues to evolve with tents that excel in various conditions and situations.  The newest member of the Arctic Oven tent line is the Arctic Oven Pipeline.  This model has a superior weight to space ratio and is great when you’re packing your gear into tight spaces, such as a dog sled.  The two Arctic Oven Pipeline models weigh less than 20 pounds and are quick and easy to set up.  They have superior functionality in high wind situations due to their short profile and the strategic stakeout locations.  These tents are designed and hand crafted by Alaska Tent & Tarp. The Seeley Slider is a Bare Bones light weight starter sled for everyone who wants to try out dog sledding without mortgaging the house. It is our J-N-A Dasher Model stripped to the main frame. It is very good for teams of 1-3 dogs. It’s runners are made of 3/4” High Density Polyethylene with Brush Bow and Handlebar made of 1/2” High Density Polyethylene. The Seeley Slider’s bolted design allows for the same great flexibility and maneuverability as on all our sleds. It also allows you to buy the Slider today and upgrade to the Dasher tomorrow by adding a Brake and Footpads. In fact, the day after tomorrow, you could even upgrade to the North Star by adding our steam bent wood skis to the same frame!! And the day after that, you could add the QCR system of runners, an Aluminum Bar Brake and a whole host of other accessories. It can handle them all! Choosing The Seeley Slider is a wise decision. You can start with it small and add whatever you like. The adaptability of the Slider never quits. Shoulder Jackets:

These are made from the same material as our leggin’s. We put 3 pockets inside so the musher can put hand warmers in these pockets to keep the shoulder muscles loose. If the dog’s shoulder muscles start to get sore then this is when we put them on the dogs. They use these when they are at check points resting. They come in many different sizes. Picket Lines

Alpine Outfitters Standard and Truck-Bar Picket Lines are custom crafted to your specific length specifications using 3/16” galvanized aircraft cable, and feature swivel-design drops (you determine length) with Swedish snaps. Our Truck-Bar Picket Line also features a heavy-duty turnbuckle to allow for proper tension adjustment.   

November/December 2011

Pure Alaska Salmon Dog Treats:

These are made with only the best ingredients. These treat have no additives or preservatives. If a child gets ahold of one of these and eats it, there is nothing harmful in there. We sell these treats in 2 different sizes 1oz & 8oz. The dogs LOVE them. Ganglines - Alpine Outfitters’ ganglines are all made to standard specifications but can be custom-made to meet your specific needs.  With your choice of colors for mainlines, tug lines, and neck lines, our gangline systems are all modular, allowing you to easily add 2-dog sections with ease, giving you the flexibility of increasing and decreasing the size of your dog team using just one basic configuration.  Tugs and necklines are finished off with high quality 5/8” bronze snaps. Order in complete 4-dog to 16-dog team systems or in 2-dog add-on sections. Our Cable Gangline System is the same design as our rope ganglines, but the mainline sections are filled with 2,000 pound tensile strength galvanized aircraft cable for maximum strength and durability.  Neck lines and tug lines are polyethylene rope but can be ordered with cable as well with the option of cable-filled tug lines upon request.


Paw Protection made from Zinc Oxide, Vaseline Malaleuca essential oil, and Thymus essential oil

Bike-Joring Attachment Mechanism -Adjustable for all kind of bikes -Avoids the gang line touching the front wheel -Flexible stainless steel design Alpine Parka

The perfect winter parka whether you are in the city working or outside enjoying the Great Outdoors. Features include: full hood, fleece lined pockets, insulated outside zipper flap, fleece-lined chin guard and an outside chest pocket. Roomy cut allows for plenty of freedom of movement. The outer shell of the Alpine Parka is Ultrex , a breathable and waterproof fabric. Insulated with Climashield a continuous polyester fiber. Climashield is an excellent insulator in any weather condition. It will not shift or compress even over an extended period of time. Should it get wet, it will maintain its insulating qualities. The Alpine Parka is machine washable. This is a great parka for any winter activity. This parka will keep you toasty through temps down to about -30 F. A full hood completes the protection from winter’s cold. Also available without a hood.

Ski-Jor Belts

For all your dog-related sports from mushing to ski-joring , we’ll provide the gear you will need. We make everything to be tough, because its no fun when a piece of gear doesn’t work at -40. There are three different styles of Ski-jor belts to choose from. These belts also work great for bike-joring as well. Canadian Kicksled A rugged northwoods version of the Norwegian style kicksled is a great sled for beginners with a 1-2 dog team. This

Canadian version gives you the look of a basket sled with its solid maple construction and laced seat back and has the convenience of a sled which you can fold up and easily take anywhere. It can also be used without dogs in the traditional Nordic style of kicksledding. Enjoy winter with this affordable, folding sled.

See You On The Trail™ Bumper Sticker

A bumper sticker is always a fun way of telling others what you’d rather be doing! Critterwoods Snow Hook This snow hook has been in production for 12 years. It is a once in a life time purchase where as it is made of almost indestructible material, tempered stainless steel that is lazer cut and tig welded for added strength with a total weight of 3½ lbs. You should only have to replace it if you lose it or just want another. The hook itself is made in a way that when pulled from the front it naturally wants to dig down and sets itself. I have got into the habit of just dropping it into the snow and letting it set itself. The best part is it will right itself. As soon as it hits the ground it will dig in and you are stopped. There have been many Critterwoods snow hooks that have made the trip to Nome as well as traveled the Yukon Quest and most of the other major events world wide.” Gary Chapman, owner.

GEAR GUIDE: 2011-2012 gear bag - Our new product is

called a Gear Bag. It is 36" tall, made out of Cordura, the bottom 1/3 is a vinyl along with the round bottom made of vinyl as well.  It is 21" in diameter, has a clear pocket on it with some velcro to keep it shut.  At the top it has webbing with a side release buckle and closes like a dry bag would. A very handy bag for moving gear from your sled to a checkpoint or tent.

Saddle Back Harness Constructed with 1" nylon webbing that is padded with neoprene around the neck and chest. Standard design includes 12" of reflective tape. Harnesses are sized by the neck size. Utilizing a side release buckle on one side and a ladder lock on the opposing side these are adjustable in length and in girth. All buckles are covered with a neoprene sleeve. Length is adjusted using a ladderloc at the base of the neck. The unique “saddle” is located on the mid-back of the dog. It allows your dog to pull without exerting downward pressure on the hips or hind legs. This can help prevent hip injuries and strains as it allows for better distribution of the load. Saddle Back Harness are a result of over 6 years of testing and development and have been used by Jamie Nelson in the 2006 Iditarod and John Baker in the 2005 and 2006 Iditarods. Saddle Back Harness shown on Jamie Nelson’s 50 lb. dog Ambler. RaceBoggan. Stiff, yet very manueverable distance racing sled, The RaceBoggan is a cross between a tobbogan and a raised tobbogan sled. It is very steerable and flexible but still has good longitudinal load support for large loads. A nice compromise between a race style sled and a toboggan. Specifications and Options: Choice of 8' or 9' runners of laminated white ash, Matrax or Rex Runners. Choice of 5' or 6 x 1/4" UHMW plastic bed, 20" width.

Mid distance, 48” bag,

with new fold down seat. Hans Gatt Handmade Sleds All sleds are custom built with a choice of either annodized aluminum or carbon fibre stanchions. There are benefits to each, talk to Hans if you would like help in deciding which is the best choice for you. All runners are reinforced with UHMW plastic. Runners come in your choice of heavy weight or light weight for 8 foot runners, all 9 foot runners are heavy weight. Every Gatt Sled is built by Hans Gatt alone. These are racing sleds and are built for the serious competitor, no matter what your actual racing experience may be. Everybody gets the same top quality sled. Gatt designs and materials result in a light weight and extremely durable racing sled. The designs come from Hans Gatt’s experience in top level racing. He uses the same sleds that he builds for his customers, other than testing out new ideas each year personally on the trail, ideas which are subsequently discarded or incorporated in the next year’s model.

Tail dragger specially developed for Iditarod. Hilleberg staika 2-person tent The Staika is all about simple – but simple does not by any means equate to “sparse.” Easy to pitch, immensely stable, remarkably spacious, and quite light, the Staika is an excellent “go to” tent for any use where sturdy strength is the high priority. We originally designed the Staika for paddle tourers, who wanted a highly stable, fully free standing tent for handling tricky pitching conditions. Since then, it has garnered a large, loyal following amongst a wide assortment of other adventurers: mountaineers, polar travelers, and ski tourers find it a supremely stable base camp tent in all conditions; bicycle tourers love its simplicity and completely free standing construction; and even regular backpackers find great comfort in its roominess and relatively light weight as well as in its strength and stability. 

November/December 2011

Hilleberg akto single person tent When we first introduced the Akto over a decade ago, we did not know that it would become as popular as it has. Although only slightly heavier than a bivy bag, the Akto offers near-luxury, all-season shelter for the solo traveler – lodging that includes a vestibule and a packed size small enough to fit into a side pocket on many packs. The Akto has true all-season capability, yet its total weight is only 1.6 kg/3 lbs 8 oz. Our tunnel design and linked inner and outer tents makes it very simple and quick to set up, and provides a high degree of stability in all conditions. The Akto is ideal any time you need the lightest weight, all condition solo tent. It is especially good for long trips of any kind, in any season, where light weight is a very high priority. And while it was not designed for extreme use in exposed and/or above tree line terrain, the Akto has proven itself on extended polar expeditions, and so will stand up well to all conditions. Scandinavian designed snow hook. V-shaped center plate, digs deeper as pull force increases. Our hook features a flat handle which is much easier to grab than the round handle that other hooks of this design have. Best hook made for use in soft snow. Never loose your team again from a popped hook! Made out of galvanized steel.Weight: 2.5 lb.

GLYCOCHARGE Annamaet GlycoCharge is a canine sports drink designed to aid in the replenishment of muscle glycogen stores following exercise. Glycogen, an essential Glycogen is one of the fuels used during strenuous exercise. Attempts to increase glycogen stores through “carbohydrate loading” in canines have had a negative impact on endurance. Post-exercise use of Annamaet GlycoCharge helps to rebuild muscle glycogen stores to pre-exercise levels. Recharged in 24 hours SKIJORING LINE

Our skijoring lines have been the top pulling lines on the market for many years now. Their superior design and durability far surpass lines manufactured by our competitors. Unlike other lines, our skijoring lines have bungee fitted in to a sleeve made out of durable tubular webbing. There is no frying, no wear and tear present the way it is with lines made out of a Poly line. Plus our two dog line features a built in bungee for each dog, which is far superior to a line fitted with one bungee only. Having a double bungee ensures good, evenly distributed pulling power and reduces tangles from dogs not pulling equally. Our skijoring line is also an ideal line for canicross (running with the dog), bikejoring, scootering, walking dogs hands free, dog trekking and as a one dog / two dog sled pulling line. EAR PROTECTOR Our Ear Protector is a must for any racing dog that suffers from chronic ear frost bite. Racing pointer crosses are especially susceptible to this condition and will benefit from wearing such protector. The Ear Protector has been designed to stay on the dog’s head while the dog is running. It is also suitable as an ear protection for any pet dog with very thin or cold sensitive ears. We also have customers, who bought our Ear Protector to put on their long eared dog (such as Basset Hound) while the dog is eating – to keep the ears out of the dog food dish. Our Ear Protector is made out of 4-way stretch, wind resistant fabric and fits snug on a dog’s head. Lonewolf Sleds are designed for incredible handling and flexibility over the roughest of trails!

With the tightest and lightest weave on the market they are the ultimate racing bootie! Tough Boots-The dryland training bootie; they are made from the toughest fabric we could find making them the best option for training on dirt. The Tough Boot is also a great option for the pet owner in need of protecting their dog from salt on city roads as they have a waterproof coating. Tough Boots w/Grip-Utilizing the same tough fabric used for our Tough Boots with the addition of a Grip fabric sewn on for better traction and added durability.

Porter’s EZ Booties are constructed from 500 denier, 100% nylon Cordura-like material and have a light, smooth nylon coating on the inside. The coated material provides some structure that helps hold the bootie open, making it easier to inset the dog’s foot as well as a longer service life. We have literally sold thousands of these booties.

There are two methods being used in the marketplace to state light output: 1. The calculation of the theoretical light output of a lighting system based on the LED-manufacturer’s stated maximum light output, and 2. The measurement of the actual light output of a lighting system using a calibrated integrating sphere. Some manufacturers use the first method, which can be deceiving because there are many other factors which contribute to usable light and available light output. It would seem that the manufacturers and products we tested use the second method, as the light output of the units was in close proportion to the listed lumens. Mushing MushingMagazine Magazine

DARK ART of Carbon Fibre By Greg Sellentin

Lighter and stronger?

Lately the use of carbon fibre

technology in the construction of dog sleds has become more commonplace. Carbon fibre is a material that consists of thin, strong crystalline filaments of carbon. Carbon fibres are used in high-strength composite materials for aircraft, automobile and architectural structures, and in other applications where light materials capable of withstanding high stress are required. It can be used to strengthen existing material, or on its own to produce a lightweight and strong component for a dog sled. ¶ I first saw carbon fibre used for the stanchions on a Norwegian brand OT sprint sled at the 1995 IFSS WC races. Relatively small diameter tubing brought on the response from obervers that it was a ridiculous material to use in such a critical area of stress in a dog sled. But, having been very familiar with the almost mythical, at the time, substance my first thought was, “Ok, here we go again.” I had seen the “lightweight arms race” take place in many sports equipment I had been involved with from windsurfing, to racing bicycles. Although the beauty of these lightweight parts and the weight savings were real, the high cost and complexity of manufacturing of such parts tended to drive the cost of participation higher and higher. ¶ Are space-age composite materials cost effective, useful, or even recommended in the construction of a dog sled, or are they overkill and just the latest trend or marketing fad? I spoke with a couple of well known and respected sled makers and the answers were interesting. 12

ne of the interesting things about Carbon Fibre (CF) is its failure characteristics. By that I mean that steel, and to some degree aluminum, will flex to a point when stressed and return to its original shape, but if forced beyond that point will result in permanent bending. Steel has the ability to be bent back after this type of stress, aluminum much less so, but CF has a “catastrophic failure characteristic” meaning it will flex to a point and return to its original shape time after time, but if forced beyond that point, will result in splintering or shattering. Granted, if used properly, this material can be very, very tough. Anyone who has watched a 6'4" NHL defenseman wind up into a slapshot from mid-ice can relate to that.


ans Gatt has experience building dog sleds dating back to before he emigrated from Austria to Canada in 1990. He started experimenting with carbon fibre parts in testing on his personal sleds about 4 years ago. Because of the complexity of laying up the carbon fibre sheets and resins, Hans uses, as other sled makers do, an off-the-shelf rectangular tubing which is intended for use as high-end hockey sticks. It turns out that the hockey stick toughness, size and shape are perfect for dog sled stanchions. Hans orders his direct from the factory without logos or plugs, just hollow tubing. “Although I have other options for having them made here near Whitehorse, YT where we have plenty of high-tech sporting industry specialist manufacturers that use CF in boats, bikes, etc, the best product and the most cost effective one was to order these hockey stick blanks.” I asked Hans if he has seen any problems associated with the lighter than aircraft aluminum material, and he emphatically said, “No. I used the same sled for 3 seasons, through some very tough Yukon Quests, and Iditarods, and haven’t seen any problems. I was initially wary of the cold, but have used it down to 60˚F below zero and haven’t experienced any failures. It might break in a hard crash, but so will wood. Most of the sleds I build are still made from aluminum. Really the only reason to use CF is the weight savings. It is a lot harder to work with, harder to drill—you have to use a core where the bolts and brackets are attached to it, and it is more expensive.” Hans explained. I had one more question for Hans - Is it worth the price difference from aluminum? He explained, “I don’t know. Every sled I make is available with CF stanchions as an option, it is an individual choice. I absolutely believe in simplicity, what keeps you out of trouble in a race is most important, that’s what counts. The weight savings is quite impressive though, if that is what you’re looking for. For comparison, I weighed each a 56 inch or 142 cm Carbon and Aluminum Stanchion. The Aluminum is 602 grams or 21.3 oz, and the CF is 308 grams or 10.8 oz. I find the difference in weight quite significant. For me, if the stanchions weren’t available commercially, if I had to have them made specially for sled building applications, it wouldn’t be cost effective.” Hans finished with.


olby Morrison of Lone Wolf Sleds echoes many of the sentiments that Hans does about CF, in that it is harder to work with than other materials. He has been using it in sleds for about 3 to 4 years, and “playing around with it” for about 6 years. He uses a Chinese made hockey stick blank that he orders in .049" wall thickness. He also has not seen any brittleness in cold weather. Kolby estimates that they are as tough as wood, and save 3 or 4 lbs maximum. The cost for all that weight savings? “Compared to wood laminated runners, the extra steps needed to both laminate in strips of carbon fibre, and then to vacuum bag the whole runner in a carbon/kevlar weave adds about $300 to the runners alone.” Kolby adds, “I can make a more flexible, yet strong runner because I can rely on the CF for strength and use less wood than a wood only laminated runner. These runners are laterally stiff, and resist warping, but have great vertical shock absorption properties.” He added. Kolby traveled to Vancouver, BC to learn the tricks of vacuum bagging CF runners from a downhill ski manufacturer. “In the future, we are going to look into making other sled parts such as brackets and stanchion junction plates out of CF.”


ody Strathe of Dog Paddle Designs uses a mix of traditional wood and high tech fibreglass/carbon fibre/kevlar epoxies to construct his beautiful yet bombproof sleds. “The feeling you get when you drive a wooden sled is different

Clockwise from top left: The runners of Cody Strathe’s Dog Paddle Designs sled start out as laminated wood. He then utilizes a cloth CF sleeve that is stretched over the runner. Epoxy resins are mixed and used to wet out the cloth. The whole runner is then encased in a larger tube that is heat shrunk around the whole assembly to squeeze out excess resin and air and to conform the CF epoxy exactly to the runner. The laminated wood stanchions are encased in clear fibreglass cloth and resin the entire length, but the higher stress ends are also encased with CF and cured in the same manner as the runners. The Danler Hornet XC-URS sprint sled weights just 17.6 lbs with a snow hook! The sled sells for over $4500 US and is a limited production run. It utilizes CF stanchions and drag mat armature as well as a new aluminum snow hook with carbide tips. This is the sled Hans Gatt used in last year’s Quest and Iditarod. It is a combination of CF stanchions and aircraft aluminum. Lonewolf Sleds, long distance tail dragger model uses hockey stick blank stanchions and vacuum bagged CF encased laminated wood runners.

than what you get when you drive an aluminum or fully CF sled. I wanted to retain some of that traditional feel. Also I’m a wood worker, that is my specialty. I find wood is also really nice to look at, but I wanted to make them stronger without adding too much extra weight, so that they are more useful to mushers who are racing. By using these exotic materials in high stress areas, I can cut down on the sizes of the wood pieces, making the whole sled even lighter. After many seasons of use both recreationally and in racing I’ve only seen one failure. It was a very hard impact and the wood inside the CF reinforcement area actually shattered but the CF didn’t–holding the whole thing together. Because of that I get a little nervous using CF alone. I’d rather make stronger sleds than lighter sleds. The CF/ kevlar combination I use on the runners is actually stronger than CF alone because the kevlar is more flexible, not as brittle as CF, and more resistant to abrasion. I’ve made them out of just kevlar and they are not stiff enough, and conversely just using CF makes them too stiff.” Cody explains. Instead of vacuum bagging his runners, which is a very time consuming process in that you can only do one set at a time, Cody has adapted a heat shrink tubing that he can do many sets at once with. The use of CF for dog sleds is understandably here to stay, and as the availability becomes more widespread, the cost of using it will inevitably be reduced. As for those OT sleds made back in the early 90’s with the thin, fragile looking CF stanchions, they are still in use today cruising around the trails in Alaska. • Mushing Magazine
