Toss the Pearl Izumi Men's MTB WRX Jacket in your pack before you rip up your local trails for the day. Its lightweight, packable design features a MTB Barrier shell and 2. 5 layer charcoal membrane that protects you from passing showers and blustery winds when you're riding over cloud draped peaks and ridgelines. The full length internal draft flap seals out wind driven rain and gusty winds from working their way inside the jacket. Armpit and hood venting actively regulate your body temperature when you're working up a sweat. Moreover, you'll find its vented hood fits comfortably over your favorite mountain bike helmet, should you need to hunker down in inclement weather.
