The lightweight, affordably priced NanoWave 45 Degree bag allows you to leave your bulky 3-season sleeping bag behind when the weather turns warm! The NanoWave 45 Degree bag has just enough insulation for warm-weather use and packs down small for backpacking convenience.
The NanoWave 45 Degree sleeping bag is insulated with a layer of Marmot's Spirafil High Loft synthetic insulation. A polyester taffeta lining offers comfort on warm summer nights and a full-length, two-way zipper allows easy venting. The NanoWave 45 Degree can also serve as an over-bag when used with other sleeping bags, effectively increasing the temperature rating and offering additional protection to the exterior of the other bag.
The Marmot NanoWave 45 Degree sleeping bag is available in Regular (fitting up to 6' 0") or Long (fitting up to 6’ 6") lengths. A compression stuff sack is included.

- Great for warmer backpacking
Likes: This bag packs smaller than any of the sleeping bags I own (including down bags), and it works well at the rated temperature or warmer. Being that it is synthetic, it is ideal for situations where the bag might get wet, such as hiking near the ocean or when kayaking. I always use it with a Cocoon silk liner which adds a few degrees warmth. Last year I used it for a week-long backpacking trip on the West Coast Trail in British Columbia and was pleased with it overall. I also used it twice in Colorado in the last couple months and it did well the first time (upper 40s overnight), but the second time it hit freezing overnight and the bag was clearly insufficient for that. If you stick to temperatures of 45˚F or warmer though, you should be fine. The glow-in-the-dark zipper pull is nice for when you need to open the bag up in the middle of the night. The stuff sack has integrated compression straps which are perfect for reducing the size of the bag when backpacking. Overall it's a great bag for the price.
Dislikes: The bag is indeed narrow as other folks have mentioned, but I think that is a tradeoff for having it pack so small. I'm 6'2" and find the regular version to be a little tight. I'd probably go with the long version if I had to choose again.
- Comfortable, narrow
Likes: The fabric used has a great feel quality and it's very comfortable. Really quick and easy to re-pack.
Dislikes: It's a bit narrow around the legs and it's definitely a warm weather bag.
- Too small at the shoulders for me
Likes: I love the size it compresses to. Very compact and light.
Dislikes: I found it very confining when zipped up. My shoulders are bound when zipped fully
Likes: small packing size and adjust price
Likes: The pack size is great, and the bag is light. Great bag for summer, or late spring. Used it twice and found it to be comfortable.
Dislikes: No dislikes yet.
Likes: Used this bag on my 2014 Appalachian Trail thru hike from Georgia to New Hampshire before switching to a heavier bag. The NanoWave 45 performed well and has a great weight to warmth ratio. The packs compresses down pretty small, about the size of a small football. The zipper is amazing and almost never snagged. For the price this is a great summer bag.
Dislikes: I used a closed cell foam sleeping pad and would feel a little chill when temperatures would fall into the 42-48 degree range. Overall though this is a great bag and you won't regret purchasing it.
Likes: Very efficient on weight! Came with a compression sack which is nice. Has a decent flap for extra insulation along the zipper.
Dislikes: Very narrow. Mummy bags are tight but this bag seems a tad slimmer than most. Could include a pocket for a blow up pillow.
