. Facts & Figures A good back protector runs from the back of the neck all the way down to the tailbone. To accommodate different riders’ sizes, all TRYONIC back protectors come in various lengths. For optimal safety it is essential that the top of the back protector does not touch the edge of your helmet. We strongly advise that you check out the size table and try different sizes at your local dealer while wearing your helmet, to ensure a perfect and optimally protective fit.
All TRYONIC back protectors comply with the guidelines for Personal Protective Equipment (PPE) described in the European Directive 89/686/EEC. This standard was updated and made more rigorous in January 2004, as the EN (European Norm) 1621-2. A project group set these norms, and TRYONIC participated, collaborating with developers and protection specialists from various brands. Under this safety standard, a back protector is tested with at least 5 impacts of 50 Joules each at strategic points, of which 2 points are deemed particularly vulnerable. An impact of 50 Joules is equal to the force transmitted by a trapezoidal weight of 5 kg on the back, dropped from a height of 1 meter. The EN1621-2 norm describes 2 levels. The less demanding is Level 1, whereas the average residual force transmitted to the back must be below 18kN (kN=kilo Newton), with a onetime impact up to 24kN. To meet the more stringent requirements for Level 2, the average residual force may not exceed 9kN, with a maximum allowed onetime impact up to 12kN. Obviously, there’s a substantial difference between Level 1 and Level 2.

REV’IT! firmly believes that any modern back protector should offer at least Level 2 protection. Most European brands subject their back protectors to these tests, but be aware: Not many pass the Level 2 standard. Be especially wary of back protectors that have not been tested at all. If first-generation back protectors were rigid and quite uncomfortable according to today’s standards, the current top models are extremely flexible, compact, light weight, and offer extremely low energy transmission levels. TRYONIC back protectors live up to your highest expectations with unsurpassed comfort— as concluded by the international press in various product comparison tests. With the introduction of the Feel3.7 and See+, we’ve resolved another issue: the problem of lack of ventilation, especially on hot summer days. The Feel3.7 incorporates a sophisticated ventilation system and great wearer comfort, thanks to its Coolmax and 3D mesh back panel, which solves this issue once and for all. The See+ also offers great venting properties at a slightly lower level then the Feel3.7.
