When the pavement's radiating heat and the sun makes the water in your bottles boil,Mavic's Cosmic Pro Women's Cycling Jersey will help you beat the heat. 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 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 ultralight side and shoulder panels and a mesh back, both of which increase breathability and comfort. 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, and snug bands at the sleeves provide a slim, aerodynamic fit that won't flap or slide up your arms.
