The lightweight, affordably priced NanoWave 50 Semi Rectangular sleeping bag is perfect for summer and warm-weather backpacking! Packing down small and weighing just 1.8 pounds, the NanoWave 50 allows you to leave your bulky 3-season bag behind!

The NanoWave 50 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 semi-rectangular cut of the Nanowave 50 offers more space to move around and 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 50 Semi Rectangular sleeping bag is available in two lengths. The Regular fits up to 6’ 0" and the Long fits up to 6" 6". A compression stuff sack is included.

Very God Bag
Reviewed by Power Fox - June 27, 2017

Likes: Lightweight and comfortable. Stuff size is pretty small. Nice color too. Took this on an overnight summer hike and it served its purpose well. No complaints!

Dislikes: None.

Packable with a Few Issues
Reviewed by Noah K. - August 20, 2016

Likes: Packabiliity, color. I have had this bag a few times, and due to packability, I really wanted it to work. However, due to a few issues, it just doesn't work for me.

Dislikes: Zipper, width.

As advertised--perfect for summer backpacking
Reviewed by Mamasita - August 4, 2015

Likes: Lightweight and small footprint. Shape allows for movement.

Dislikes: Not much cushion but that's to be expected for being so light.

Reviewed by Anonymous Backcountry Edge Customer - July 29, 2013

Likes: Purchased for youngster who didn't want a sleeping bag that was too hot. This is "perfect" she says. And the zipper doesn't stick (unlike prior Marmot bag). Great color too and relatively compact

Dislikes: Hard for kids to get the bag back into the sack.
