The Men's Mammut Manaslu Jacket shares its name with the eighth tallest mountain in the world and is every bit as burly. Reinforced with a Gore Windstopper 3 layer membrane, this jacket protects you from piercing winds to keep you going until you make it to the top. Despite providing excellent defense from the wind, the Manaslu still maintains a high level of breathability and mobility thanks to its SOFtech shell. Mammut also armed this jacket with a vertically and horizontally adjustable, helmet compatible hood, two backpack and climbing harness compatible front pockets, hook and loop cuffs, and an adjustable hem that helps keep out unsavory weather conditions. Even if you're climbing when the sun is shining, the Manaslu is still working, providing you with UV 50 sun protection.
