The pros wanted the thinnest, lightest warmers from us that protect from the wind and are as waterproof as possible. We've pared the covers down to the bone, but they're still a functional piece of clothing. The material adapts precisely to the helmet and protects against wind and water. A silicone hem on the inside of the top of the gaiter cuff ensures that the gaiters don't get rained into from above and that they stay in place, and the long zipper makes it easy to put on. The bottom of the sleeve is made of durable material. It is an aero sleeve that works.
