Mammut Rainspeed Ultralight HS Jacket Men's

Catering to your need for speed, the Mammut Men's Rainspeed Ultralight HS Jacket is built to combat Mother Nature's worst when running in alpine environments. The Rainspeed features Gore Tex's Active 2 layer shell, resulting in a highly breathable and waterproof design that is one of the lightest shells Gore Tex produces. Part of what sets this technology apart is it forgoes the use a textile face fabric and puts the membrane directly on the outside of the jacket to maximize breathability. To protect the membrane, Mammut incorporated a permanent Shake Dry finish, so you won't have to worry about grease, dirt, or wetting obstructing the breathability of the membrane. The Rainspeed packs down easily into its chest pocket, so you to chuck it in your running pack and forget about it when the sun comes out to play.
