Marmot NanoWave 55 Sleeping Bag: 55 Degree Synthetic

I bought this bag looking for a warm weather alternative to my warmer bag and the description had everything I was looking for. When I got the bag I liked the weight but, true to other reviews, getting it in and out of the storage bag was near impossible. They need to make the storage bag a slight bit bigger and put a strap on the bottom so you have a place to hold onto when pulling it out. The length of the bag was great but when I got in and zipped it up there was no room to move. I know it is a mummy bag but a little extra room would be nice. I am 6'2" 195 and consider myself to be average girthiness. Anyone who is a little on the chunky side should stear clear of this bag. I am returning it before I even use it as it will not work for me.

It's lightweight, it's compact. But, it definitely is not adequate for cooler nights and is not comfortable in line with the EN ratings.

Great, compact sleeping bag for warm summer nights! Even on cooler nights, I had a little extra blanket in my pack - lined my sleeping bag with it, and slept great (coupled with my down sweater and long johns, of course)!

this bag is so small but perfect for summer camping. if your looking for finding more space then this is definitely the right bag.

Marmot is awesome. This bag packs down so small and is under 2lbs. It’s rating is 55°f and can go down to 33°f. I have tested it out in 30°f weather. It was a lil bit chilly but with proper layers I was fine. I take this bag everywhere with me. It is so small it just fits into any backpack or bag. Love the Nanowave series. I would love to try out the other temp bags. ReviewbyDrew

Love this sleeping bag! It’s lightweight and compact making it easy to pack. I’ve used it several times in the desert. It keeps me nice and comfortable during the lower night temperatures. I would highly recommend this product!

This is the perfect bag for a Summer backpacking trip. It is thinner than a typical sleeping bag so it packs down really small and only weighs 1.5 lbs. It's also great to leave in your car for an emergency blanket or for sleeping on a friend's couch.
All of Marmot's products are very high quality and come with a lifetime warranty. For the price this is an awesome sleeping bag!

This bag is perfect if you are looking for a reasonably priced summer sleeping bag. I have also used this as a liner for cold weather camping. Marmot really did a great job on this bag.

I live in Alabama and this is a perfect bag for late spring-early fall. I needed something other than just my 20 degree winter bag and this was a great addition. It packs down decently small but for the price point it's what you'd expect.

This is a light weight compact summer bag, perfect for backpacking in the Grand Canyon.

I've used this in the heat of summer nights in Moab, 30 degree weather in CO, and 60-70 degree weather in Texas. It does the job I've sought it for. For the colder weather, I just used a liner and bundled a little more with my long johns. I am a firm believer that no matter which sleeping bag you get, use a liner for longevity. I've hung dry it, and my wife has also washed it a couple of times. The semi-mummy sleeping bags are my favorite as they give me the perfect balance between snug and flexibility. It compacts pretty small, think the size of a small watermelon or an oil rig mans giant traveling mug.

I have owned it for over a year now and used it on many trips. Despite the gimmicky first impression this thing is a steal compared to a expensive down bag at least for us with budgets of under $100. It is great for summer camping65-50 and i use it down to 30 degrees when paired with adventure medical kit bivy, inflatable sleeping pad and appropriate layers( full base layer, synthetic t-shirt, fleece jacket. full synthetic pants). I cut the compression straps off of the stuff bag because they were unnecessary for me because the bag is already small and it packs easier without a bunch of webbing every where. I also think it looks better without them. Also when sleeping in a hammock using it like a quilt ( fully unziped with a foot box) is easy with the small hood design.
Pros- small
-light
- reasonably accurate on warmth
-easy paired with other sleep accessories( bivy/pad)
-comfortable material
-nice hood design
-great price

Cons-compression straps were not useful for me
-even large is too small for people over 6ft 3in

Packs down super small to fit in my pack or in my truck. Very comfortable.

I bought this bag for my grandchildren to camp in their back yard. I like how small it is when in storage. Seems to keep them comfortable, warm and cozy. I would recommend it to all my friends.

Well its exactly as its described, It works great for the temperature range is says it does. 50 degrees is almost too cold though. I tried it out on a 40 degree night and it was pure misery. Even through my bad experiences, the last one was better as it only dropped down to the mid 50s. I was warm enough to actually get some sleep that time. The thing I really like about it however, and moving forward into an arizona summer, is that its SUPER light. Its also tiny when stuffed in the compression sack it comes with. I'm looking forward to the warmer nights here in a few weeks. However once fall rolls around ill be buying something rated for much colder temps.

Needed a bag that I could use here in south Texas and this was it. Compresses into the sack provided easily and is just a little bit bigger than my Nalgene bottle. Think I might buy a thicker one for cooler months.

I work in a national forest for 8 days straight, two weeks a month and brought this bag with me all summer. Super light weight and compact. What makes this bag great is the material on the inside. It feels less like a sleeping bag and more like some sort of amazing bed sheets, perfect for hot sticky nights in the Georgia mountains, because we all know that we aren't wearing much in our bags in the summer. Perfect for hot sleepers like myself. The downside is that my version doesn't zip all the way open, and I bought it this summer. Way better than the REI bag rated to the same.

I have yet to take the bag out to test the limits of the 55 degree rating but will do so next week and can update then.



The packability is AWESOME and, contrary to some other reviews, I had no trouble getting the bag back in the provided stuff sack.

Initial impressions:

The long is definitely long enough (I'm 6'1).

Even though its not a full mummy, its a bit narrow, most noticeably around the knees, but enough room overall.

The bag is warmer than the VERY thin material would make you think but yet to be tested in under 55 degrees.

Backpacking and camping in Georgia summers is a hot, sweaty, sticky affair. Even a 35 degree bag is just too hot to be comfortable. Car camping, you just take a blanket, but what about when you need something lighter and more compact for backpacking?

This bag is perfect. It's light enough, perfect temperature rating, extremely compact, and the material isn't all plasticky and sticky. What's not to love?

It comes with a nice compression sack, and is seriously smaller than a Nalgene bottle when compressed. It's a bit heavy for what it is (55 degree down bag would weigh probably half this, but cost $200+), but compared to other 35 or 40 degree down bags, it's competitive. Plus, it can get wet or at least damp and no worries with the synthetic insulation.

The material is great, it's less like an ultralight synthetic weave, and more of a microfiber cotton. Really comfortable and not sweaty. The length is good, 5'10 and I fit comfortably in the regular with a few inches to spare.

Backpacking in July, I started the night out with it draped over me like a quilt, and in the middle of the rainy night I got a bit chilly so I zipped it up and was great for the rest of the night. It's perfect for summer in the south.

My only gripes are that it could be a bit lighter (maybe it doesn't need a hood?), and the zipper doesn't go all the way to the bottom, so you can't use it like a big quilt. Otherwise great bag at a great price.

This is the best bag for any warm weather camping. I have used this bag in 45 degree weather with no problem! It packs down very small and is great for warm weather backpacking. Anything under 40 degrees you will want a warmer bag, this is for your summer camping and is worth the $.
