Stick to the essentials this season with the ingenious warmth-toweight performance of Simms’ Downunder Merino layering system. The Mid Zip Top regulates body temps across high-altitude ups and downs, while flat seam construction combined with flatlock stitching delivers natural stretch and comfort for a full range of fishing motions. $109.95
Championed by Simms’ endorsed professional guides, the Mid Top is an all-season workhorse built for stalking the stingiest Henry’s Fork sippers to full-bore on the oars. Take advantage of articulated elbows for a quick double-haul to the far bank, a zippered chest pocket for convenient storage, and classic ¼-zip styling for absolute on-off changeups. An updated fit uses durable 4-way stretch fleece fabric that bundles warmth, breathability, and wicking with fullrange fishing mobility. $89.95
