The Tenax Jacket is constructed with Activa Plus GTB multi layer material, which incorporates a flexible membrane that is windproof, waterproof and breathable. The rear panel and back of the arms are made of Super Roubaix, a micro fiber fabric that is very elastic to enhance fit and allows breathability to help regulate your core temperature. The jacket is anatomically cut for a great fit throughout the range of motion when cycling. Three external rear pockets with two additional zippered compartments with pull tabs offer lots of room for storage. A large reflective strip across the pockets, reflective chevrons at the shoulders and reflective Giordana logos guarantee increased visibility for safety. Super Roubaix cuffs, an extra high collar and the full length front zipper with internal wind flap seal out the elements. Gripper elastic at the waist holds the jacket in place. Recommended for temperatures under 50F.
