Great Summer Bag, But Narrow

I have had this bag for two summers now, I'm 5'9",180lb so pretty average, and this bag is slightly too narrow at the shoulders, I very rarely zip past the elbows. I love the weight and size though. Will probably give it to my son to replace his kids version and find a slightly wider bag for myself. If you are broader than normal is avoid this bag.

Compact Light Sleeping Bag

Was very happy when I received this sleeping bag. It is compact, lightweight and will work great for summer camping. Also the fabric has a soft feel so will be great to sleep on instead of the typical plastic feel of synthetic material. I have not used the bag yet, but will update after use.

Great For Warm Weather Camping

Packs up small and was perfect for nights dipping into the low 50s

Everything You Want In A Warm Weather Bag

Been using my Nanowave 45 for 5+ years now and its all you'll need in a warm weather sleeping bag: light, low volume, and warm.

Probably Rated Closer To 50 Degrees

I know that these ratings tend to vary given how well the person using the sleeping bag handles the cold and other weather factors. But after this past weekend, I'm fairly confident this is closer rated to 50 degrees than 45. I was camping around Asheville, NC this weekend for 3 nights and tested this out in actually cold weather (40s and 50s versus 60s and 70s, which is what I tested it at last time). It worked fairly well but I give it about a B- for how it handles actually cold weather. The tempertures for the weekend were between 45ish and 55ish and on the 45ish night I was bundled up in 2 tops, a beanie, very thick Smartwool socks and Smartwool thermal base layer pants and I was just warm enough. Even at 55ish I was wearing extra clothes to keep me warm and, as far as I'm concerned, if a sleeping bag is rated for a temperature, I should be able to use it in just my underwear...or at least very minimal clothing. Still, I love that it's so compact and otherwise well-made. It definitely does the trick for almost 45 degrees.

It Is Very Small And Convenient For My Camping Hik

I have used it once already and it's very comfortable and kept me cozy

It's All About The Weight

A good quality lightweight bag. The temperature range for this bag is restricted. It doesn't unzip all the way down. So your feet have to be inside or on top of the bag. If you wanted to press the temperature range into the low 40's, would have to sleep bundled up in clothing. However I tried this and it didn't work for me. I am an average height person weighing 145 pounds - but it was just too restrictive with all my clothes on. So in my opinion, bag is only useful in cool - warm weather starting in the 50's. That said, this is a top quality bag with a top quality stuff sack!

Lasted The Test Of Time

Very happy with this sleeping bag for warm evenings that extend into chilly nights - spring, fall and high elevation summer camping. I took this summer backpacking though Alaska and it packs down in it’s cinch sack and is lightweight. When I used the conch sack as a daypack in town, one of the outfitters said he had the same one and did the same thing with it (used as daypack). Great minds think alike. Super comfortable and love the material. Not a sweaty layer of plastic at all. Machine washes great.

Big Surprise In Small Package

This bag stuffs very small and is surprisingly light. Good quality. Too cold right now to use it outside. Will update a sleeping experience later.

Super Cozy!

We bought this for our 10-year-old for her birthday so she can join us on backpacking trips. It packs tight, is lightweight, and purty darn warm!

Great Summer Bag

Love this for warmer nights. I was camping 4 nights on the Green River Utah. One night got a bit too cold for this bag, but I have no idea what the temp was. Could have been 40 degrees. Not sure. Other nights were maybe 50 degrees at night and I was perfectly comfortable

Nice Lightweight Summer Bag

Perfect lightweight summer sleeping bag. Fits compactly in my pack, doesn't take up much room at all. Only issue is the weight listed at 1lb 1.3oz but even the outside of the compression sack has it at 1lb 13oz. On top of that, I weighed it at home with the compression sack and it's 2lb 4oz. So misleading info on the site for sure.

4 Year Review

I've had this bag for over 4 years now, and it's accompanied me on many, many backpacking trips. I've probably slept a cumulative 3+ months in this thing. It's not the warmest bag, of course, but it's perfect for the warmer summer months.

Great, Light Weight Bag!

My family has had three of these light weight Marmot Nanowave 45 bags for years, and they have never disappointed us. We have used them on backpacking outings in the warmer months several times, and we have even used them like a liner in a heavier bag on colder outings. They back down small, the zippers are easy to use, and they have just held up very well to the abuse my three teenage, BSA Boy Scouts have put them through.

Great, Simple Sleeping Bag

I got this bag as a summer bag to use in Colorado. The bag is great and packs down perfectly. The bag is a little narrow but if you’re used to sleeping in a mummy style bag it’s just fine.
