The Arenberg Forest has a special place in the heart of Hincapie Sportswear's namesake. Though he never won the race in which it features, his passion for it is unmatched, so you'd expect any gear that bears its name to reflect that. The Arenberg Zero Knee Warmers don't disappoint. In a race renowned for its brutal conditions, the Arenberg Zero is what you want on your knees. For 2014, Hincapie has updated its old Arenberg line to Arenberg Zero. The name change owes to the addition of a new material on the knee and lower thigh, TourTek Zero X2, which combines an accommodating four way stretch with fleece lining, water resistance, and full wind resistance. Your knees are one of the most vulnerable spots on your body during cold weather rides, so this extra protection which doesn't make an appearance in the corresponding arm warmers will not go unappreciated. The warmers are lined with panels of BodE Thermal Heat, another four way stretch fabric that's soft on your skin and is the most insulating material in Hincapie's arsenal. The flat seams ensure comfort while the dual sided gripper at the top keeps them in place on your legs and under your shorts. The Hincapie Sportswear Arenberg Zero Knee Warmers are available in five sizes ranging from X Small to X Large in the colors Black and White.
