Why We Like The Never Summer Sleeping Bag

Summer might bring mild weather, but it also brings crowded trails, so we use frigid temps to our advantage and head to the mountains with Marmot's Never Summer 0 Degree Down Sleeping Bag in winter weather. Stuffed full of Marmot's water-resistant Down Defender 650-fill down, the Never Summer keeps us warm when temperatures drop to single digits, and its DWR coating adds a bit more protection from light snow flurries that might accumulate along the walls of the tent.

Always warm

[This review was collected as part of a promotion.] I bought 2 of these in 2019 and have used them multiple times. They work very well at keeping your body heat and you warm right up in them in about 5 min. Used them at temps down to 0. They are also easy to pack and durable so far.

22 years old and going strong

[This review was collected as part of a promotion.] I purchased a left-zip Never Summer zero degree bag from Hudson Trail Outfitters in 2000 back before I was even a retail employee there. 22 years later, it is still my go-to winter camping bag. Yes, I only winter camp one night each year, but I haven't missed a trip once in the past 20 years since a group of us started the tradition of a late-Nov to early-Feb trip annually back in 2000. this bag has seen nearly every peak in the GW&TJ National Forests and most of Dolly Sods. It has kept me comfortable in Fahrenheit weather down to the low teens and kept me safe and relatively warm to temps even lower still. The lowest I've experienced with this bag was -11 Fahrenheit overnight in Ramsey's Draft Wilderness, and many of my friends decided to upgrade their gear after that trip, but my Marmot bag not only held its own, but I was actually able to get several hours of sleep overnight while everyone else shivered and froze through the night. While I would say that taking a 22-year-old version of this bag into zero degree weather might not be perfect, the it is probably the best value for the money you will be able to find out there today. So, in sum, if the materials and upgrades over the past 22 years mean that this bag is even more formidable than my ancient version, then do yourself a favor and grab one for your next cold-weather excursion!!

Great toasty bag

[This review was collected as part of a promotion.] This bag was well worth the money. I've used it several times in cold weather with the coldest night down to 8 degrees F. With the moisture wicking clothes I slept in along with my facemask, I slept great in this bag. I would definitely but it again.

Love this sleeping bag

[This review was collected as part of a promotion.] I always take this bag to the Sierra Nevada. So far the coldest I've been in was at least 20 something degrees. I have another Marmot sleeping bag that is 20 degrees. I will always buy Marmot because their quality is so good!

Tested down to -15°C / 5°F

[This review was collected as part of a promotion.] Taken this bag out on many mountaineering trips in the PNW, so far it has kept me toasty warm down to -15°C/5°F - with R7 sleeping mat system. So far very happy. The small zippered pocket on the inside top is awesome for keeping small important items close. Could use a smaller lighter stuff sack though.

4 stars, just a bit big and heavy

[This review was collected as part of a promotion.] A tad heavy, but really pretty great all-around for me on solo multi-day colder mountain backpacking.

Comfortable, warm, tad bit tight in the legs

[This review was collected as part of a promotion.] Bought this for my wife. We tested it out in one night when it dropped to 17 degrees, and she stayed warm. Not the lightest, but packs small enough and when planning for cold weather. Weight isn't my biggest factor over comfort. The only thing she mentioned what the cut by the legs seemed a little tight. There's not much room if you're looking at layering much. This is dependent on size of course. Overall, a good product.
