The road is just about the hottest place you can be on a baking summer afternoon, but Mavic's Cosmic Pro Women's Sleeveless Jersey helps keep things comfortable. Made primarily from 37. 5 fabric, a polyester that's been designed to to instantly attract and wick moisture, the Cosmic Pro is your best bet for staying dry on the hottest, most tire melting days of summer. It uses a specially knit wicking matrix to transport vapor up to five times faster than standard polyester. It also has lightweight side and shoulder panels and a mesh back, both of which provide increased breathability and comfort. The sleeveless design not only enhances cooling, but it also avoids awkward tan lines and gives you full range of motion. The Cosmic Pro covers all the standard jersey bases, too. Three rearpockets hold all the small items you want to keep close, the full length front zipper provides plenty of ventilation, and UPF protection helps save your skin when you're riding under a baking sun. There's even a media port to route headphones, so you can have your tunes turned up or stay connected to your support vehicle.
