Product Reviews
Rated 5 out of 5 by from Like being in Heaven. You won’t regret buying this [This review was collected as part of a promotion.] I FINALLY HAVE ONE! I’ve wanted a Marmot bag for over 30 years and it’s worth every penny. Marmot has used their years of experience perfecting this sleeping bag. I love the features and boot bag and extra foot room. I am 6 foot and got the 6’6” bag- zippers don’t snag with their technology. Side zips are great. You will love this bag. I used mine with double groundsheets and recommend 1 for insulation - while I was not in a tent.

Rated 5 out of 5 by from Absolutely worth it! I was hesitant to buy with the price tag but I live out in the middle of nowhere oregon up in the mountains at 5000ft and go to around 8000 all the time for winter camping, this thing had been amazing!

Rated 5 out of 5 by from N [This review was collected as part of a promotion.] I live in Alaska and I backpack all year round and I have an unheated tent in the Winter. The previous CWM was awesome but this bag is 5 plus. I love the central zipper, I love the inside pocket to put my cell phone and headlamp in so they do not die from frozen batteries. I love the gills that not only limit condensation without losing critical warmth.I love the way it lofts up, it, like its predecesser, is a giant marshmallow. I took it to a fundraising sleep out (in the snow) last week. It was about 2F so this was plenty warm without a shelter. I am a short guy but I buy a long bag,as I put my boots in a trashbag inside the footbox at bedtime, so I do not put on frozen boots in the a.m. When its really cold, you can ruin a good time with frostbite,

Rated 5 out of 5 by from Very good cold weather bag Hiked into the mount Zerkel wilderness area. On an Elk hunt temperature down to /zero degrees Fahrenheit with a light air mattress had no problems at all warm as toast . The short zipper makes it a little tough to get into for me I'm 5'11" 2 15 pounds but overall very happy with the bags performance All the equipment I purchased from Moose jaw worked just as advertised very happy with the company

Rated 5 out of 5 by from Super warm bag and it compress down small! [This review was collected as part of a promotion.] I just got the new CWM -40 bag right before my trip to climb Denali. I get cold easily when the Temps fall below zero so I wanted to make sure I had a warm bag. On Denali at 14,000 feet and above the Temps ranged from 0 to -15 degrees from 7pm to 8am. I spent 11 nights on the mountain and I only zipped up the bag 1 of 11 nights. I was toasty warm the whole time. I was also very please how much I could compress the bag to fit into my pack. I highly recommend this bag if you get cold of night or need a super cold weather bag.

 I’m 5’9.  I know the regular will fit “up to 6ft” but would I be better off with a long.  My last new bag wasn’t close to fitting a 6’ person and ended up selling after one use.  

Asked by: Rescue Guy
Hey there, thanks for your question. If youre right on the line, or even close to it, it's better to size up to the Long. Having an extra few inches at the bottom to wiggle your toes can make a huge difference in comfort. It can also come in handy as a warm spot for a water bottle (so it doesn't freeze overnight) or extra base layers you want to keep warm for the morning. Basically, its better to be short in a long bag, than tall in a short bag. I hope this helps!
