Voler's knee warmers provide versatility & protection from the elements, & are perfect to keep those hard-working knee joints warm and happy! This technical item is made with 9.5 oz. Dryline - a wicking fabric that pulls chilling moisture away from the skin to keep you ultra-warm, dry and comfortable. As the temperature rises, they are easily removed and fit in a jersey pocket. The articulated design prevents uncomfortable bunching behind the knee & helps keep them in place (the seam is worn behind the knee.) Also featuring woven gripper at both hems to ensure that they stay put.
