For those of us who always sleep cold, the Marmot Never Summer is the ideal 3-season sleeping bag. Insulated with 600+ goose down, you can cinch the collar down and stay cozy warm as the temperatures drop or unzip the full side zipper for more air flow if the temperature stays warm. Stretch tricot baffles allow for more movement and "Feely" draw cords let you make adjustments without exposing your hands to the cold. For those of you who always sleep warm, the Never Summer makes an excellent 4-season choice for mild climates.

Great Sleeping Bag
December 04, 2011

Took this bag with me to the top of Kilimanjaro where the overnight temps were near or below zero and never had a problem with warmth. It was light, easy to stuff into its sack for packing every morning and the zipper wasn't as much of an issue as I've read in other reviews. It should be noted, though, that my gf had a hard time getting her bag into the carrying sack each morning but I'm not sure if that was more her or the sleeping bag. The only concern I had the whole trip was getting it wet and reducing the effectiveness of the down but we never had an issue with rain or snow.

Pros: Build quality, Performance, Ease of use, Great value, easy to pack/carry

Wonderful dry warmth, smooth main and lining material, packs fairly small, excellent construction, versatility for all seasons - overall expected Marmot quality at a reasonable price

Nice Bag, reasonably priced
January 08, 2011

I've used this bag a few times this winter in the mid atlantic appalachians. It is definitely a nice bag, much warmer than my Never Winter 30deg bag I've had for years. I got tired of being cold in the winter, and went to the 0deg bag. I'm biased toward Marmot gear, I've used their stuff for years. My Never Winter bag has lasted 12+ years, and I expect this new Never Summer bag to last as long. Fit/finish/quality is high, marmot standard. I'm 5-10 - 180lbs and fit comfortably in the bag. The leg space is typical of a mummy style bag; this is not a large rectangle sleeping bag. However, I feel I have just the right amount of leg space. If I do start to overheat a little, I just unzip the bag halfway and all is well. The bag works well even when damp/wet, which is why I typically choose down over synthetic, but that's my opinion. It "feels" like its actually warmer when it is damp. Probably just the relative humidity inside the bag as body heat dries it off. I would recommend this bag to anyone who finds themselves getting cold(shivers) in a 30 degree bag. I skipped the 15deg versions and opted for the added warmth of a zero, specifically becasue I intend to increase my winter snow camping activities.

Pros: Great design, Build quality, Performance, Ease of use, Cons: none
