We updated the fit to further reduce pedaling restriction and increase thermal protection on the outside of the upper thigh, into the hip area. We also added a zippered ankle, which makes the warmers easier to strip and stow while in the saddle. On days you wear them for the entire ride, these new warmers ride more securely courtesy of our skinGrip Finish, a low-bulk silicone grip that allows for seamless layering and raw cut hems. Light compression, moderate insulation, aggressive breathability, and an aerodynamic fit.
