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 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.

  • Snagless draft tube
  • Two-way zipper sliders
  • Blanket construction
  • Two hang loops
  • Compression stuff sack included
  • Feely drawcords
  • Zipper garage

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: 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.
