With this warm, lightweight functional underwear, you can now perform at even higher levels in cold conditions. Thanks to innovative 3D circular knitting technology, these base layer tights are made from stretchy, form-fitting material with minimal seams. The seamless construction makes the leggings comfortable against the skin—without any chafing seams that can be bothersome during long runs, extended bike rides, and intense cross-country skiing sessions. Effect by Odlo: The functional fiber "Effect" integrated into the material with silver ions stops the growth of bacteria and effectively prevents unpleasant odors. "Effect" works without chemicals, is completely skin-friendly, and offers maximum climate comfort. Evolution Warm promotes thermal insulation and moisture transfer precisely where these functions are needed, thanks to the circular knitting technology.
