Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Perfect moderate weather bag
4 years ago
[This review was collected as part of a promotion.] I hiked a thousand miles on the Appalachian Trail this year I was carrying a 15° bag in the summer it was horrible I never got in it I switched it out for this nano bag changed my life completely night's got cool enough to slip into it without sweating and getting sticky... Back rolls down to about the size of a 1 l water bottle fantastic edition for a long distance hiker... Could use it all the way into the 50° f range which happened at times above treeline elevation I will always use this bag for years to come for temperatures down into the 50s at night lightweight washes easy silky comfort... Definitely my top five favorite pieces of gear.

Nanowave 55, My New Standard
1 year ago
[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.

Packs small!
4 years ago
[This review was collected as part of a promotion.] I just bought this to add to my collection of different temperature bikepacking sleeping bags. I wanted something for warmer/summer season sleeping here in Arizona. And it needed to pack small. This bag performed perfectly for all my needs. Super comfy, packs small, weight is low. Would definitely recommend for anyone looking to fulfill those needs. And at this great price, it’s totally worth adding to your collection of bags! Be aware; it ONLY performs well in the temperature it’s rated for or warmer. I did have one night where it dropped a little below 55°, and I felt it. I had to get up in the middle of the night and put a layer of clothes on. -Photo shows how small it’s packed. That bag is about 7ltr and has the Nanowave, an inflatable sleeping pad, and inflatable pillow inside.

Exactly what I needed
5 years ago
I live in Texas and I needed a lightweight sleeping bag that would not be too hot for our nights into early summer or fall.... the rest of the summer its just too hot period lol. It was so compact and compressed nicely into this little pouch perfect for backpacking. I slept on top of it for a few hours, but it finally cooled down a tad and i was definitely in it when I woke up in the morning.

Nano wave 55
3 years ago
[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.

why do i need a review title?
4 years ago
I heard good things about marmot gear and warranty. The sleeping bag is comfortable and well made there is enough room for me and i’m 6’3”. The carry sack could maybe be a little bigger as the sleeping bag is somewhat challenging to stuff in the carry sack (but it is nice and compact.) overall great sleeping bag. I live in Kenya and have not been eaten by a lion or stepped on by a giraffe while in this sleeping bag. Thanks Marmot!

Perfect for my needs.
5 years ago
[This review was collected as part of a promotion.] I work in rural and remote Alaska and often stay in gov bunkhouses. We will often bring a sleeping bag (and my own pillow case and towel) to save time having to wash and dry sheets we used on the last day. It cab be a time suck when you are only staying for one or two nights. Anyway I got tired of sweating in my other bags and bought this. Lighter, more compact and not as constricting as most mummy bags. Love it!

Packs down small and is surprisingly soft
3 years ago
[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.

Great cool weather bag
1 year ago
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.
