Race day is never comfortable. It's miles and miles of hard effort. The Pearl Izumi Elite in R Cool SL Jersey works hard to keep you cool so that your body can focus on the day ahead. The In R Cool Tri jersey combines several fabrics for optimal fit and cooling. Elite Transfer In R Cool fabric features a Lycra composition that provides light compression for your muscles. And, while you may not see the need for compression on your torso, after a few hours in the aerobars, you'll be glad for some extra support. This fabric is also treated with Coldblack, which helps to reflect the heat for the sun, even off of dark fabrics. By doing this, it keeps your skin cooler. Textured Elite Aero fabric is placed over the shoulders so that you'll have less drag during the bike leg. And, when every second counts small watt savings will make or break your race. Both fabrics dry quickly once you are out of the swim and continue to wick moisture to keep you comfortable on the bike and run. A form fit jersey, the panels have been shaped so that it doesn't bunch or move while in riding position. Flatlock stitching eliminates chafing against your skin. For additional ventilation, a 10inch zipper is included. Two easy access back pockets hold your race day nutrition. The Pearl Izumi Wlite In R Cool Tri SL Jersey Women's does not come with a bra insert. It is available in five sizes from X Small to X Large and in the colors: Scuba bluescreaming yellow, Hot pinkstormy, and Blackscuba blue.
