Get into the Marmot Men's 8000 Meter Insulated Suit for extended expeditions on the world's coldest and highest mountains. With durable reinforcements and a waterproof shell, this suit prepares you for the demands of climbing at altitude. The 8000 Meter Suit features a combination of 800 fill goose down and Primaloft Sport in a baffled construction to retain insulation where you need it. The fully waterproof MemBrain shell keeps you and the down insulation protected from fierce storms at high camp. Marmot included articulated knees, elbows, and seat for full mobility, and Lycra suspenders so you can remove the top of the suit while keeping the bottoms on. A hydration system pouch holds your water bottle on pre dawn summit pushes and a full front zip and venting side zips allow for moisture management and easy in and out.
