Chilly rides? Not with this under layer. It's built smart, stretchy and seam-free, with different bits for warmth and wicking just where you need them. 3D knit keeps you cosy, wicks sweat fast, and stops any rub. Skin-tight fit, so no drafts. A good base layer is the starting point for a great ride. This one's got your back when the days are short and the air's nippy. Engineered to move with you, no bunching, no rubbing, just comfort. Chuck it on, stay warm, and stay psyched. Layer up and ride on.
