Why We Like The NanoWave 55 Sleeping Bag

Whether we're traveling by boat, bike, or foot, we bring along the Marmot NanoWave 55 Sleeping Bag for all our summer adventures. Its packable, lightweight design and compression stuff sack allow us to easily carry it in a backpack without taking up much space or adding too much weight. The Spirafil insulation ensures we'll stay comfortable on chilly, humid summer nights. A full-length zipper that extends around the toe box allows us to transform the sleeping bag into a blanket when the nights don't quite cool off, so we can sleep well throughout the whole adventure.

Nanowave 55, My New Standard

[This review was collected as part of a promotion.] I’ve owned a number of sleeping bags, from the big box bulky/one temp and size for all to premium makes. Having taken up kayaking with the possibility of camping overnights, I realized I needed a good summer bag that would pack easy without weighing me down. Marmot’s Nanowave 55 (Long) made a great first impression; lighter and significantly smaller than my previous backpacking bag with its compression straps. The zipper was smooth, interior was roomy enough to fidget a bit, and length was as advertised. That last one is greatly appreciated by those of us over 6’ tall as not every item sold runs true to advertised length. If you’re in need of a good sleeping bag I can highly recommend the Nanowave as a fine fit.

Great cool weather bag

This is a great sleeping bag for cooler weather. It’s compact enough when rolled up to take anywhere but still roomy enough for all 6’2” of me to sleep comfortably in it. I liked it so much I purchased the standard length for my wife for camping.

Great bag for the tropics

[This review was collected as part of a promotion.] At first I didn't think I'd need a bag in the tropics, but this thing comes in handy--perfect for a cool night after you've acclimatized, or for the cold night stuck in an airport.

Nano wave 55

[This review was collected as part of a promotion.] Build and materials are great. Packs very small and is a great go everywhere bag for uncold weather. Negatives are that is it not very wide, making it less than perfect for side sleepers. It’s also unfortunate the zipper isn’t long enough to vent your feet. I’m sure Marmot made these decision to save weight and packed volume on the bag, but in my case I’d trade a couple ounces for that. Also, be aware the inside material has a soft feel, which is nice but doesn’t allow a sleeper to shift and turn over in the bag without the bag following. Again, a side sleeper problem. Overall, a good solution to my need for a non-down warm weather bag that works in wet environments such as long-distance sailing.

Packs down small and is surprisingly soft

[This review was collected as part of a promotion.] I've had this bag for 5 years now. I bought it to guide trips in the summer. It packs easily into the bag and with the compression straps it fits nicely in my drybag. The fabric is surprisingly soft and it has a nice weight to it. It's holding up well-no tears or loss of warmth after years of heavy use.

Lightweight

[This review was collected as part of a promotion.] This is an awesome lightweight sleeping bag. It is compact, lightweight, and comfortable. It lives under my truck seat May through October with a hammock and rain fly.

Bikepacking

Small and compact for bikepacking. However, a little tight and constrictive in the shoulders.

Awesome

[This review was collected as part of a promotion.] I purchased two of these for my kids for 3 season camping. Excellent quality, great size, and the included compression sack makes it phenomenally small. Perfect
