Marmot Col MemBrain Sleeping Bag -

When you're up over 14k feet or exploring the deep recesses of the alpine backcountry, you need a serious sleep system to get you through your inactive times. Enter the Marmot Col MemBrain -20F Sleeping Bag. Baffled with 800+ fill down insulation, it will trap warm air near your body for unmatched warmth. It is light and compressible so it won't take up much pack space. On trips where you need a -20 bag, I'm guessing pack space is at a premium. The rest of your pack will probably be taken up by hot cocoa mix and marshmallows. The waterproof/breathable MemBrain® fabric seperates the Col MemBrain from the pack; it is durable and resistant to the elements.

Cabelas
Trust your cold-weather comfort to a Marmot bag created specifically for the extremes of high-altitude mountaineering. The 800+ fill-power goose down is independently tested and certified by a lab, and retested before construction to ensure the goose down meets the highest standards for warmth and overall performance.

The nine vertical baffles in the chest section create maximum down control, ensuring that rolling from side to side won’t shift the down. Nautilus hood wraps around your head to reduce heat loss. Six baffle chambers of down promote better down control and fit. Hood cord is positioned for easy access. Velcro®-free face muff creates a warm down gasket around your face and keeps the drawcord out of the way. Stretch tricot fabric in the baffles increases strength.

Marmot Col MemBrain Sleeping Bag Reviews:

Positive Reviews:

I bought this bag 2 weeks ago and have used it on two separate trips already. I think I have the earlier model, but it looks like nothing has changed except the color. This bag is extremely toasty! I had a zero degree sythetic before this and the insulation was paper thin! On my first outing temps were about 20-25 degrees to start out the night and I was too hot! I had half my body hanging out and was only wearing a t shirt. As it cooled down I was able to put the rest of my body in the bag and by morning I was able to zip the bag up. Temps probably got down to zero degrees and I was toasty warm. On my second outing it was a little colder and I was more comfortable. Temps probably got down to -5 or so. I zipped it up all the way and was toaty warm all night in only a t shirt. This bag packs well compared to my synthetic. It takes a while to poof up so just be patient. Little to absolutely no down has leaked thus far. As long as I take good care of this bag I anticipate on using this bag for year and years! The waterproof membarane seems to work, althought I havent really tested it. Drips bead up and roll off quite well. Bottom line: great bag, spendy but will eventually pay for itself.

I'm not someone that's perhaps as qualified as a lot of these other reviews in reviewing and testing a -20 bag. However I did just get done camping in the Andes in winter and the bag was amazing. I get super cold at night too. Mind you, temperatures never reached anything close enough to completely test the -20 claim on the bag. It was comforting to know and feel confident that I could however. I slept in the bag every night for 6 weeks--even in warm houses. it's a great size , super comfortable (I'm 5'7- bought the regular), and could be my new prized possession.

My Favorite Piece of Gear

People laugh at me when I tell them what this bag is rated, but they don't understand how cold I sleep. I used to own a -5 degree synthetic bag and would be cold sleeping in well-heated hotel rooms in it. I bought this for a season working at high elevations in the Sierra Nevadas and haven't regretted it once. Yes, it's heavier than most down bags you'll come across but being able to sleep outside of my tent in near-freezing temperatures and watch the stars in comfort each night made it well worth the weight. I will never be cold again!
JackNikon at REI on 12/12/2010

I have camped in almost every condition with this bag and absolutely love it. The only complaint I have is that it can get too warm! A quick unzip though and life is good again. This bag is coated with Marmot's version of Gore-tex (MemBrain) and it keeps all external moisture out of the bag. I can easily pack it down into a size L Sea to Summit eVent compression dry sack. If you are wanting a bombproof bag that wont let you get cold, consider this one. It does have a steeper price tag but is worth every penny.

Steve Mitchell at Backcountry.com on 08/19/2010

This bag is pricey but I have never regretted it for a second. I have used it on many winter trips and it keeps me very warm and dry. I love the waterproof shell it seems to work great and gives me that extra peace of mind. If it is not extreme winter weather I just sleep in this bag with a tarp over me. If it is heavier wind/snow/cold I bring the bivy. If you winter camp this bag is a great idea.

I camped two nights above 20,000 feet on Mt. Aconcagua in Argentina, when it was so cold that exhaling made it snow inside the tent. This bag made for comfortable sleeping when used atop a combination of foam and inflatable pads. It really needs a good compression stuff sack to control the bulk in your pack, so be sure to get one of those as well.

Great Bag

I used this bag in -11 F, with a wind chill that was -32F. I live in North Dakota. I slept in a bivy, with a 1.5in Thermarest pad. I stayed very warm and even cracked my sleeping bag open. This is a very godo bag and I am excited to try it in cooler temps.
Stew23 at REI on 02/02/2012

Just gave the Col it's first bout of trials hiking Mount Marcy on the weekend. I was warm through the night camping part ways along the trail both before, and after attacking the summit.
Squeezes down not half bad for such a warm bag either.

Brad Fowler at Backcountry.com on 10/31/2011

I've used this about a dozen times and it is really great. Camped in lean-too's at -15 and un-heated cabins at -10 and i've been cozy while everyone else is just getting by. Love it, and love Marmot bags!

Gunnar at Backcountry.com on 01/03/2013

Marmot bags rule, this super warm and spacious bag kept me warm for two months in Alaska sleeping in a snow cave and winter camping. Its amazing how warm it is and how small it compresses.

Negative Reviews:

I've had this bag 5 winters now and it has been warm but it has some major problems. I take very good care of it and store it properly but the membrain lining is just peeling off the nylon around the head and top. It is no longer waterproof. You can see the down right through the nylon. This bag is ok for a year or two but for that much money I really expected it to last a little longer. If you want a quality product buy a Western Mountaineering bag, they are very nice and around the same price. You will have no issues what so ever, plus they are US made. WM also has a really good warranty. I will never again buy a Marmot product of any kind. Friends of mine have had all sorts of problems with jackets and other gear they make. Definitely a company to avoid.
