The ONE Leg Warmer takes the same fabric platform built for Velocio's tights and scales it down into a thinner, lighter layer. There's no zipper and no gripper band, just a matte, ultra-soft knit with enough stretch to move through a full pedal stroke without bunching. We keep a pair rolled in a jersey pocket for any ride that starts colder than it finishes. What Our Gearhead(R) Experts Are Saying:"I've descended for twenty minutes straight and never once reached down to check if these had slipped."
