The Powerstretch® mid layer has the only fleece with body-hugging four-way stretch and exceptionally high moisture management. The fabric has two unique surfaces: the durable, non-pilling outer surface which resists abrasion and the soft inside velour pile that wicks perspiration. Bulky fleece is often used under waders and jackets, but to maintain freedom of movement and lightness Powerstretch® is the best choice of all. With our new cut we have maximized the performance to be absolutely perfect. Once you go for Vision Powerstretch® you enter a totally new world and there is no way back after that. The new 2008 top comes with our new redesigned chest pocket.
