    I recently used my new Marmot bag on a camping trip in the Colorado Rockies and was very happy with it! It was comfortable, with enough space to shove clothes at my feet/down the side to keep warm for the morning; it was easy to move around in when changing position and easy to quickly get in and out of. Most importantly - it was very warm! I can easily pack it away in the travel bag and the storage bag allows me to keep it safe when not using it. A great purchase.

    I took this backpacking for the first time over the weekend. It didn't come with a compression bag so I purchased one to get it small enough. It was in the 30s and I stayed warm. I'm 5'2" and I was very pleased with the length too. And I love the color.

    I spent 3 nights with this bag with evenings in the high 40's. It wasn't warm enough for me. I can't imagine being out in it in 20 degree weather. My boyfriend also has a 20 degree down bag, and his is much thicker - it has more down in it. For warmer weather it would be good - it's a good size for me - I'm 5'2" and packs up very small. But I'm sending it back.

    This marmot down bag is beautiful. It looks so much better than the picture and seems plenty warm enough. Before I ordered I read the reviews and was concerned about the "cold spots" one reviewer mentioned. When I first got it I noticed that it was totally flat in a spot at the shoulder area but fluffing it worked for me and now the loft seems evenly distributed. Sizewise too it's great since I am only 5'2"...not sure how it would work for tall women. I'm really glad I ordered this bag and know I'll keep it a long time.

    I haven't used it yet but it looks great. Its light and warm. I plan to use on our family hiking trip. I will write a better review after I use it.

  • “Can this bag zip together with your Item #3046V|Marmot 20°F Flathead Down Sleeping Bag - 600 Fill Power, Mummy?|Do you have other bags that can zip together?”
    Asked by Stephen from United States on 1/28/2013 12:00:00 AM
    • They will not zip together.|In order to be able to zip two mummy bags together you need one bag to be a right rip and the other to be a left zip. Currently we do not have any bags available in both zips. So at this time we have no bags that can be zipped together.

About Marmot

Conceived in a university dorm room by a pair of climbing buddies, Marmot Mountain Works first opened its doors in the spring of 1974 in Grand Junction, Colorado. At the time, the base of operations was a 100-year-old stone building. That same year, the first Marmot down jacket was produced specifically for an action flick called “The Eiger Sanction,” starring legendary actor Clint Eastwood. In the four decades since, Marmot has continued to engineer reliable gear that exceeds the expectations of outdoor athletes. Today, Marmot tents, backpacks, outerwear, clothing and Marmot sleeping bags are still pushing the limits in the planet’s most challenging conditions, from the summits of the world’s highest mountains to the deepest river basins.
