Textured fabric along the shoulders and back is intended to help air track along the rider's upper body for longer before separating, which creates additional drag.

Cooling Sleeves

The concept of the cooling sleeve is nothing new, and Castelli has new twist on the concept. Temperature-activated design on the sleeves turn light in color when the sleeves warm up (think the opposite of a Coors Light can). It may be gimmicky, but the idea is to give the rider a visual reminder to douse the arms with water.
