Marmot Never Summer Sleeping Bag: 0 Degree Down

Just took this to the Colorado rockies in June, the temp got down to 22 F and i was able to sleep with the bag open! the down was comfy and I had plenty of room for my feet, no complaints here.

This is a sweet bag for the price. I haven't tested it in 0 degree weather yet, so it's hard to tell how it will preform in those temperatures. However, it has kept me toasty in the mid 30's (that's saying a lot, I turn into a pop sickle at night). It packs down small *enough* for backpacking if you have a solid compression sack, but there are definitely smaller bags out there at a higher price point. Overall I'm super stoked on this bag and would recommend it.

I've been wanting to splurge on a down winter bag for years. Luckily, this wasn't even much of a splurge. It's so comfortable I take it on warmer trips and lay on top of it. I bought a separate stuff sack, which allows it to be compressed smaller than the one included. The coldest I have used it in is about 20 F. The first night, I was rather cold. The second night, I put a hot water bottle in the bottom of the bag and was warm from the get go. If you don't do that, it takes a while for your body heat to warm up the bag. The bottom is very roomy so you can store your boots, slippers, and fuel. I am 5'10" and had just enough room for items in the bottom with the long sleeping bag.

Brought for my girlfriend she refused to get out of the bag!!
Well made good price awesome. Stuff sack a bit big but no big deal. Awesome.

Love this sleeping bag! I got one for me and my twin sister and we use these bags all spring, summer and fall to camp in the mountains and for colder desert nights. They pack up small enough for us.

Had this bag up at Garibaldi Lake, just south of Whistler, May 4th. It got down to just below 30 degrees at about 4900 ft elevation. Our tent was on 7 feet of snow pack. I was in a T shirt, thermal bottoms and light weight wool socks and slept great. 5'8" 180, Regular.

I used this sleeping bag while car camping where temps dipped down to 30-35 degrees at night and the bag kept me toasty warm all night. The inside of the sleeping bag is very soft and comfortable and the zippers were very easy to zip up and down. I would recommend this bag to anyone especially for the quality and price of the bag.

I got this bag and used it on a backpacking trip to Capitol reef, I woke up with snow on the bag and felt like i was in Bali inside. packs nice, not bad weight, good fit!

So comfortable and warm. Its rated for 0 degrees, so only use this bag in fall and winter obviously. If you're going to be camping in very cold regions, get a bag rated for -15 or lower if you run cold... On super cold nights I freeze my ass off in this bag. Other than that, I love the color and the material. Its very durable and lightweight, compact-able. Yeah.

very comfortable and warm bag especially at this weight and price point. Kept me comfortable in the teens (farenheit) with no additional liner necessary. Construction quality seems good but haven't used it long enough to comment on durability yet.

For as big and warm as this thing is I was surprised at how packable it was. I got to use it a couple times this fall and was very pleased with it's performance. I got the extra long one, I'm 6', and more than enough room. It was around 30° so I didn't get near the bags rating limit but from what I can tell the bag is solid.

Used: in Maine on the AT for 1 month. Shenandoahs on the AT for another cold week.

Size: I'm 5ft6in, and 130lbs. I originally bought the bag in the long version, but then exchanged it for the regular. Much better for me, the feet are actually in the foot box. It is a little tight around the shoulders IF you wanted to stretch. I tend to stay compact so it was perfect.

TEMPERATURE: Very cozy and warm. I spent 1 week in the Shenandoahs and the temperatures were close to 0Celsius (32F) at night. I was eager to get into the bag at night. I still had my first layer on and I was very cozy and slept well. The oustide was a little humid in the morning, but dried quickly and actually never made it to the inside anyways. The fluffy-ness of the down makes it cushiony, so very comfy.

USE: I toss and turn a lot. The bag turned with me, yet compared to another bag I have, I never feel the zippers on this one, even if completely on it at night. The strings to pull the bag around your face is ok. There's only 1, but the top string is different than the bottom string. I found it a bit annoying to pull one vs. the other, as they go through the same clip. With practice, it'll be ok.

side note: it has that distinct chemical smell for a brand new product. It still has the smell. I like the smell but it could annoy some.


All in all, I love it!

ps: I do agree the little bag it comes with is useless. Buy your own compression bag, or just shuv it in the bag and compress with the rest on top! haha

The bag is great for what you pay for it. I sweated my butt off in long johns and a t-shirt on 20 degree nights. Based on that it should keep me comfortable if I'm wearing all my layers when the temps dip into the single digits.

Here's why I didn't give it 5 stars:
1. The stuff sack it comes with is useless. Buy a real compression sack because the bag has a mind of its own and really prefers to take up as much space as it can. I tried putting it in the flimsy little stuff sack it came with and within thirty seconds it had popped out and was spread out across my floor.
2. I do NOT fit in the regular bag. I'm 5'10 and 160 pounds, pretty slim guy, most of the weight is scrawny muscle. But I am too long for the bag. If I push my feet hard against the bottom of the bag, my girlfriend can work the hood over my head, but I feel like super trapped. It's also nearly skin tight around my thighs. I can't spread my legs more than a couple inches. I get the phrase mummy bag means something, but this is one heck of a tight bag (or maybe I'm just claustrophobic).

Pros: toasty, light enough for the price, compresses well (with a real compression sack)
Cons: runs small, the fabric doesn't feel super strong.

I do a fair amount of winter camping and this bag is usually what I take with me. I use a 45 degree bag inside of this one if I feel the temps might be getting really low. With a 45 degree bag as a liner I've slept out in the -30's in Yellowstone on top of 10+ feet of snow. It works well and is really durable. I am always looking at getting another one when mine finally has had it but it keeps on trucking.

The Marmot Never Summer sleeping bag does exactly what it's meant to do. I used this on my last backpacking adventure and it was fantastic! It was a little too warm one night, which kind of made it tough to sleep, but I still can't complain when you're too warm. It did it's job well!
The only complaint I have regarding this sleeping bag is the size of the stuff sack. It's very long. Too long for my pack. If you are going to use this bag on backpacking trips, I would recommend that you invest in a compression sack to make it easier to fit in your pack.
The bag is super light, which makes it easy for backpackers. When you take it out of your stuff sack, it takes maybe 10 minutes to "fluff" to its normal size.
I definitely recommend this bag to anyone that is interested in buying it! Great buy!

This is a killer deal for a 0 degree bag. I am 5'9 and the regular bag fits very well. The 650 fill insulation is slightly heaver than other bags, but I can barely tell the difference and the price point is much better.

I slept in this bag for 8 nights on Mt. Shuksan, in the northern cascades. Lowest temps got was in the teens. This bag kept me very warm, especially in the feet. I usually have cold feet when I sleep, but the footbox on this bag is well insulated, so I had cozy toes at night.
The head was not as warm. I slept with a thicker hat than normal. I think the weight of my head compressed the down and caused my head to be cold. Not an issue, I just wore a hat.
The water-resistance was great. I expect that, since it's a brand new bag. My tent leaked something fierce, and every morning my tent contents were wet. The outside of the bag would be covered with condensation, and some parts were even laying in a small pool of water at times. The interior of the bag stayed dry the whole time, keeping me nice and warm.
I'd definitely recommend this bag. Just bring a hat.

I used this several nights in 15-20F degree weather and it was superb! I have limited experience with real Down fill bags and have traditionally used only synthetic bags. As expected, this bag is considerably lighter, packs smaller and is very comfortable through varying temperature ranges. The zipper seems well designed to try and minimize snagging. The zipper baffles did a great job at keeping out the creeping cold.

Contents includes both a standard stuff sack and large storage sack. I used a large Sea-to-Summit eVent compression dry sack and it packed down to half the volume of the stuff sack.

Fitment:
I am 5'11", 165lbs and opted for the "long" bag just to have some extra room. I probably could have been comfortable in the standard length bag but am happy with the extra lenght and minimal added weight. The footbox was ample for my size 12US feet and the hood was also a good size for my 7 3/8" noggin.

Cons: Slightly heavier than a 800+ Down bag

Pros: Good fit, great quality, packs small, handles damp environments well, excellent price for performance

Recommendations:
Good for Backpacking, Winter Sports, Moderate Mountaineering
