Pearl Izumi Elite Thermal Arm Warmers provide versatile warmth for your knees and quads, ideal when paired with your favorite shorts or bibs in changing conditions. These knee warmers feature anatomic construction that eliminates bunching. Elastic plus a silicone gripper keeps the knee warmers securely placed.
These are great .... except they will not stay up. There is silicon tape on the outside at the top that is supposed to grip your shorts but there isn't any inside to grip you leg. So these things do not stay up. Other than that, they are great. I've actually considered taking them to a tailor and having that piece put in.
Pros: well built, great protection, right size
Cons: won't stay up
