Castelli Pro Seamless 2 Knee/Leg Warmers Crafted from a unique blend of polyester, nylon and Lycra®, the Castelli Pro Seamless 2 Knee/Leg Warmers give impressive thermal performance without causing overheating. Their mid-weight construction offers just the right amount of insulation for cool starts and changing temperatures. The high-stretch fabric delivers a supportive, second-skin fit that moves effortlessly with every pedal stroke. Fully seamless construction further enhances comfort by eliminating pressure points and reducing the risk of chafing on longer rides. Designed to be versatile, the Pro Seamless 2 warmers can be adjusted depending on your needs. Pull them up the thigh to add warmth over knees and upper thigh, or position them just above the bib short gripper to create full leg coverage when conditions demand extra warmth over the lower leg. When the temperature rises, they fold down to an incredibly compact size, making them easy to stash in a jersey pocket. For cyclists looking for one accessory that delivers comfort, packability and all-season flexibility, the Castelli Espresso 2 Knee/Leg Warmers are a smart investment for every ride.
