Full body insulation for Earth’s most frigid places.

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.

Unanswered Question

Just trying to compare suit vs 8000m parka+pants: what's the dawn fill weight of this suit? Also is this suit really 10D outer fabric, while both 8000m parka and pants are 30D ?

Very warm and comfortable

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XL

This is my favorite article of winter clothing. When I come home from work I change into this suit and immediately get warm and cozy. Even wearing only underwear beneath this suit I stay warm whether I'm working on the computer, watching television or if I have to occasionally go outside for a minute or so. It vents pretty good so if I get too warm I can regulate myself. Whenever it snows I put on more layers underneath and go sit outside and watch in total comfort. Best part is on weekends if I fall asleep watching tv I don't worry about waking up cold. Great loungewear.

Just as expected

  • Familiarity: I've used it several times

I never thought I'd own one of these but the great price was too good to pass up. It is everything I was expecting. Very well made and high quality. It has a great storage bag so it won't take up quite as much room in the closet. I'll be looking forward to putting it to use later this winter.


    This snowsuit is very warm and lightweight. It wasn't cheap but this suit is great.
