The Thermal Sleeves work to keep you warm on colder rides. Constructed from a four-way stretch fabric, the sleeves feature a fully brushed inside to enhance warmth, and fully flatlock seams to increase comfort. The sleeve outers have been treated with a fluorocarbon-free DWR treatment to provide protection from light rain showers. Silicone grippers featuring the POC logo are included at the upper opening to ensure the sleeves stay securely in place. A reflective POC logo is included on the left arm to improve visibility in low light.
