Castelli Flanders Wind Long Sleeve Baselayer
Inspired by the riders in the Tour of Flanders, this wind-blocking baselayer lets you ride in surprisingly cold weather with only a jersey to cover it. Windproof stretch fabric on front repels water and manages moisture. 3D structure rib-knit on back and main body gives you an exceptional fit and channels sweat away from your skin to eliminate clamminess. 4-way stretch sleeves enhance moving comfort and microfiber mesh underarms provide additional cooling.
