Weighing in at a mere five ounces, the Mavic Cosmic Pro H20 Jacket offers highly stashable, lightweight protection from spring showers. Its featherweight 37. 5 membrane keeps you pleasantly dry through sopping-wet weather, while zippered ventilation areas enhance breathability, ensuring you're not a sweaty mess in damp, humid conditions. Fully sealed seams prevent the intrusion of outside moisture, further fortifying the jacket's outer shell from wind-blasted rain and soaking-wet conditions. Moreover, the jacket's slim, close-to-body fit was cut specifically for the Condor-JLT team, so it prevents flapping when you're riding fast in inclement weather. Plus, Mavic placed the waterproof zippered closure on the side, so you don't have jacket and jersey zips pressing in the same place.
