The exacting women's fit, wicking performance, and comfort of this new-classic style is further optimized with the addition of In-R-Cool technology and fast drying Transfer Minerale technology. In-R-Cool reflects the sun's rays and reduce fabric surface temperature by up to 35º F /14º C under direct sunlight. In-R-Cool helps to regulate body temperature to get more performance and enjoyment out of hot weather riding. Minerale is a natural technology that exceptionally wicks and evaporates moisture.

Pressure Relief Technology (PRT) optimizes riding comfort, blood flow and athletic performance while active carbon yarns improve thermoregulation and eliminate static-induced fatigue.
My girlfriend and I each have three pairs of these. Each year we throw the worst pair away and but new ones. This year (2014) PI decided to change the sizing of these, but not other models of shorts. Both of us had to return ours because they were too small. This is a real bummer for on-line shoppers who need to be able to order products with consistent sizing.
