Marmot Men's Nanowave 50°F/10°C Semi Rec Sleeping Bag

[This review was collected as part of a promotion.] I don’t have any photos, but this bag has lasted me through thick and thin, it’s a great bag for south Florida because it’s always so hot here but we have the occasional chilly night. It’s super well made and I’ve never had any issues with ripping, or the zippers getting snagged like so many other bags I’ve had.

Nice, packs small, summer bag. Like the all around zipper and roomy foot box.

First of all, the quality of the materials is good, it's lightweight. But I've decided to return it after I used it twice. The reason for return is simple - it does not work for temperatures specified in the product description. Both nights when I used it, the temperature hasn't gone below 60 degrees and I was freezing inside the sleeping bag. I felt the cold air was going inside the sleeping bag from the whole surface of the bag. It does not work even for 60 degrees, it won't work for 50. Very disappointed by the product. At the same time, I have Marmot Tungsten tent and I love it.

Small and compact, this fit into a small backpack in my carry on luggage, jist what I was looking for!

I bought 2 of these sleeping bags for my wife and I to use while travelling this Summer. We also own an earlier model of a Marmot Summer bag, the Trestles Trails bag with a Dri-Clime like liner and a water repellent nylon outer, with no hood. But those bags weren't warm enough if temps dipped below 50 degrees, even after being zipped together into a double wide sleeping bag. The Nanowave 50 Semi Rectangular comes in only Left Zip. I was able to zip 2 of these bags together into a double wide bag, and the zippers work fine. The only issue is that one bag will have the hood flop over onto your chest, but the other bag will have its hood down and ready for use. If more warmth is needed, our old Trestle Trails bags can fit over the Nanowave 50 as a double bag. That lowers the comfort level down another 10 degrees or to about 40 degrees. Why doesn't Marmot make the Long model in Left Zip and the Regular model in Right Zip, so couples can mate the bags together into a double wide bag? The Nanowave 50 Long Semi Rectangular is fairly roomy, even for a big guy like me (6 feet 2 inches/ 290 pounds). It comes with a very nice compression stuff sack that cinches the bag down to about the size of a football. This fits well inside our Deuter 32 ACT Trail and Deuter ACT Trail SL 28 liter packs, which we use as carry-on travel bags. I think these will be the perfect sleeping bags for Summer hiking, travelling with overnight stays in a Kozy Kabin at KOA campgrounds, or crashing on a couch in the cooler weather.

I’m hoping to find other bags with this semi rec shape. I roll from side to back when I sleep a lot and tighter mummybags I feel like the bag is restricting or gets twisted on my legs... not this one, I love the shape. 50 deg is accurate. At 45 deg I wish I had a little more, at 50 or warmer it is all I need. Small and compact. Great summer bag in Washington and use it as a second bag on snow camps in the winter. Also like that it fully unzips at the bottom to use as a blanket. Material is nice.

[This review was collected as part of a promotion.] I purchased this sleeping bag for warm weather here in Southern California for car camping and the sleeping bag meet my expectations. It is extremely lightweight and when compressed, it is the size of a large burrito :) At first, I was skeptical due to the size but was amazed of the durability and ability to keep warmth with such a thin design.
