Marmot NanoWave 55 Sleeping Bag: 55 Degree Synthetic

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 $.

I have been looking at getting a warm weather sleeping bag. I picked this bag up for spring and summer camping. This bag is perfect! It packs up small and it kept me warm throughout the night where it got down to about 50 degrees. If you're looking for a good summer bag pick this up!

I recently had the opportunity to use the NanoWave 55 which I just purchased this spring. I used it fro a week straight. It worked very well. The temps were a little warm, but I was comfortable up to about 60-65 at which point it was a little warm. The coldest it got was about 55 and I slept like a baby. I need to try it at the colder range of its rating to see how it does there before giving it the 5th star.



It does pack really small and the only complaint I have is I have not been able to get it back into the original compression sack. I have used a third party 10L compression sack instead.

I bought this bag to replace my 15 year-old sleeping bag and went from a 32 degree bag to this (I run hot).

The first time I used it I was thrilled:

A.) it was the size of my nalgene bottle and therefore fit into my saddle bags on my bike very easily.

B.) It's incredibly comfortable and warm for its size. ( I ended up trying to sleep in a hammock with no pad in 40 degree weather, got a little cold, but not the bag's fault - it worked for most of the night!)



Great product, recommended it to my mother, would buy again.

i was looking for a small compact and cheaper bag for summer backpacking trips and car camping. i wanted something with good quality but also a good price point. this bag did just that. the zipper works good, but does catch often. the hood gives you that little extra on nights you need it. i have even used it as a liner car camping on cold nights for my 3 season bag.

I needed a sleeping bag for the summer when it's warm. This works perfectly for me. It's good for nights when you fall asleep on top of it or with it unzipped then when you wake up in the middle of the night you can zip it up and not get all sweaty. The 2 way zipper works well for letting your legs stick out to cool off. This also comes with a stuff/compression sack. It will compress tiny, perfect for warm weather backpacking. I will also use this as a liner or 2nd layer for a winter camping bag. It also looks cool and the gray color is nice.
