Marmot Col Men's -20°F/-29°C Sleeping Bag

[This review was collected as part of a promotion.] I bought this bag for winter use in the Himalayas. I was in temperatutes colder than -20. This bag was so good that I could not zip it up or I would overheat even in -20!!! Marmot is the only brand of sleeping bag that I will every spend money on. I bought 5 different brands to test for this trip and Marmot CRUSHED them all. Fory test I slept in the snow in my backyard in my boxers with NOTHING but the bag I was testing that night, not even a sleeping pad! There was NO comparison. Marmot was the only bag I was comfortable enough to sleep through the night without ever waking up! Very Warm, lightweight, extremely comfortable, great compression for packing, high loft insulation for extra comfort that will keep you super toasty warm in the coldest weather. Even melting snow under me did not seep through, it kept me dry and hot as heaven. Don't waste your money on any other brand of sleeping bag. Marmot bags are better than #1, they are in a league of their own! There is no comparison out there. Trust me I tried, sleeping raw in the Alaskan winter snow in my yard NOTHING came close to Marmot in every category! MARMOT BAGS FOR LIFE!!!

Used the bag for a fall hunt in the Brooks Range, Alaska - 150 mile north of the Arctic Circle. It was warm and comfortable. Night time temps were in the low teens to maybe single digits and I was always comfortable, never wanting for more. The arm holes are nice for reading.

[This review was collected as part of a promotion.] Used on an overnight in Feb. on Mount Washington, NH. Temp -10 F, wind 50-60 mph. Bag kept me warm. Wish I could have used arm holes, but it was too cold! This bag did the job, and can't wait to continue to put it through its paces. Got the long to keep my single-lined boots in the bag with me at night. At 5' 9", still had plenty of room.

This is a big, warm bag. High quality and I love the double zipper for the arms.

[This review was collected as part of a promotion.] I bought my Marnot Col -20 originally for climbing the volcanos of the PNW. On Rainier for example I was actually hot and had to vent the bag a fair amount which I considers a good thing because I could just sleep like a rock even on very cold nights. It’s extremely comfortable for sure and I find any excuse to use it. The waterproofing is quite impressive, when I first got the bag I just laid it out back and dumped nalgenes on it and sure enough that bag was bone dry. I enjoyed this bag so much I also got a 0* and will soon pick up a 20* as well. I’d say if this bag is in your budget and you’re eyeballing a -20 for all weather conditions you just can’t go wrong here.

This bag is warm and comfortable. The size for me is perfect. One minor complaint. I would like it better if the main zip was a little longer towards the foot box but like I said, it’s a very small issue.
