The Skins C400 Wind Vest has an active membrane that let's a bit of wind through on warmer days and seals out the elements on cooler days. Made from the latest windproof fabric that increases breath-ability at higher temperatures and becomes more rigid and insulating when it gets colder, the SKINS C400 Men's Wind Vest acts just like your own personal thermostat.

Mesh inserts on the back help reduce heat buildup to keep you dry and comfortable. And with handy openings that let you reach your back pockets, you'll still be able to get to your energy bar.
