The Pearl Izumi P.R.O. In-R-Cool Women's Short Sleeve Jerseythrows down the gauntlet for other jerseys vying for the title of best hot weather women?s jersey. One hot, humid ride in the hills with this jersey and you?ll see what we mean. Pearl Izumi has upped the ante by incorporating the advanced Minerale and In-R-Cool technologies into the Transfer fabric that is used for many of the best Pearl Izumi jerseys. The Transfer fabric boasts 15 times the surface area of typical poly weaves to facilitate the wicking and evaporation of moisture. The Minerale treatment that is permanently added to the Transfer fabric utilizes natural volcanic minerals to boost the evaporative cooling and offer odor protection and UV protection. On top of that, the In-R-Cool technology keeps you cooler by reflecting the sun?s rays and effectively reducing the surface temperature of the fabric by up to 35 degrees Fahrenheit for cool comfort in the blazing sun. If you are like us, you prefer the flexibility that a full-zip jersey offers. Whether we want to wear bibs and so need the ability to take off the jersey without pulling it over our heads for mid-ride rest stops or we want to be able to ventilate to our heart?s content, a full zipper is the way to go. And don?t worry about struggling to get the zipper up and down ? this one moves like a silky dream. With a nod to the ladies? smaller backs Pearl Izumi has specially designed the 3 ?n 2 back pocket construction that includes two pockets that carry larger items like your wallet, pump, gel packs and phone, while a third pocket with a zipper has been hidden within the two so that you can keep your keys and other small essentials safe and separate from the rest. This makes it possible to hide away those things like keys that you won?t need to have access to for much of the ride, but simply can?t be without or lose. And as with the men?s version, extra support at the back pockets will keep them from sagging. The usual well-placed Pearl Izumi reflective elements will keep you visible at dusk. The Pearl Izumi P.R.O. In-R-Cool Women? Short Sleeve Jersey comes in White, True Red and Black/Lime. It is available in X-Small through XX-Large.
