Cozy Comfy Tall

It’s hard to find a warm sleeping bag in my size, this fits the bill.

Great Purchase

Went to Northern New Mexico for summer camp and while days are warm, the nights are not. This bag did the job. When it is really gold, a liner makes it perfect.

Decent Budget Bag.

I used this bag down to 33F and was comfortable with a light, long sleeve Merino base layer top only. It packs down pretty well for a Synthetic Bag. Way better than any Big box store offerings I have seen. I also have the Nanowave 45F which packs even smaller but would not be good much below the 45F rating. I recommend this Nanowave line if you are on a budget and not dealing with temps below 30F.

Very Thin, Not Warm At 10°c

Mid winter, dressed, room temperature around 10°C and I was almost chilly inside this sleeping bag. Marmot is a good quality company but this bag is very thin for a rated 3.4°C.

Not Warm. Too Big. Sad.

Marmot messed up big-time with this one. As other reviews have noted, it didn't keep me warm even in ~40 degree weather. Brought this on a week-long excursion in Utah and Colorado and was downright SHIVERING every night, even though it only dropped to in anything below 36, unable to sleep, even with my down jacket and wool socks on, with the bag "sealed" shut over my head. I imagine you'd freeze in 25 degree weather! Hoping I can return this.

Great Bag!

This is a great 3 season bag! Light and packable for a synthetic. Very roomy. At six feet tall, 180 pounds, 34 waist, large hips and broad shoulders, I had plenty of room to sleep on my back and side. I had no problem with length even with my air pillow tucked into the hood. The temperature rating on the bag felt good in 30°F weather, keeping me nice and warm, paired with a sleeping pad rated at 4.1 R value. A nice soft feel and glow in the dark zipper pulls are also good bonuses.

Not As Described

I purchased this bag because it stated the zipper was full length and extends around end of foot box. This is not true. It doesn’t even go to the end of the foot box never mind around the foot box. I’m very disappointed.

Not As Warm As Advertised

We bought this bag for our daughter and were surprised by its thinness. We just took a trip to Lassen where the nights were 35-40 degrees F. My daughter complained of being cold the first night, so she and I switched bags. I was freezing every night of the trip even with all of my warmest clothes on. We were backpacking and did not have the ability to add more layers or switch out gear. I hope that Marmot changes the temperature rating on this bag. Even with temperatures at the level they say should be comfortable, this bag did not keep us warm enough.

Happy I Got The Longer Version.

I'm 5’11" and am very happy I opted for the long version. Sleeping bag seems to be warm enough for 3 season camping. Packs down just small enough for my hike in pack. I am happy to take this on more hiking/canoeing trips.

Great Bag!

Great bag! Only reason I dropped a star is it's a bit light for fall camping, I used a liner though and that helped wonderfully! Really enjoy the bag!

Excellent Design And Comfort

I purchased 2 of the Nanowave 25’s and put them to the test in mid 30 degree weather with no additional blankets or sleeping bag liner. Impressed! Is all I will say! We woke up to ice on the perimeter of the tent and was nice and warm only utilizing the sleeping bag and a rolled up sweater as a pillow for 2 nights.
