Great
Husband got this for backpacking. He has recommended it to multiple people. It is warm, lightweight, and has help up incredibly well to all of his outdoor activities. He is an avid backpacker/hunter and so it is important for him to have something that checks all of those boxes.

Worth the money!
My only dislike is the fact that it never fluffs up. Normal stuff sack sleeping bags compact and then fluff up after you let them air out. This doesn’t do that. Stays relatively flat. It is very well made though and keeps me warm whenever I use it so it definitely does what they say it should do otherwise.

Great sleeping bag!
When I recieved this sleeping bag, I was very doubtful of the comfort and warmth because it was in such a small package. I was amazed! It is super light weight, but also very warm and comfy! Amazing compact, light weight sleeping bag that provides warmth and comfort!

Not Durable, Shell Fails, Down Comes Out
Purchased May 2022. Made in China. Never machine washed or harsh chemicals. Always stored fully expanded. 2-3 day tent camping trips using air mattress. No hard use. Bag was good until forth use, then down started coming out first a little. Checked bag, no holes. On fifth use large volume of down started to come out of shell all over me and tent. So much that had to end camping trip. Having owned several down bags this was first time ever saw this happen. Five very light duty uses and finished. Not reparable as down was coming out everywhere on shell, but no visible holes. To trash, only three month warranty. This is a serious product and manufacturing defect that wasted my money and time and ruined my trip. If you want a durable long lasting bag, look else where. Don't believe this is genuine mountaintop product. Scammed.

Super comfortable summertime bag
This mummy bag is extremely comfortable, light, and compresses nicely. The measurements are accurate, so I fit perfectly inside. This is my new summertime sleeping bag. I slept comfortably at about 50 degrees Fahrenheit in my hammock.

Expecting 32 degree sleeping bag but bag received good for 20 degrees!
I do not like temperature rating at 0-20 degrees when expecting 32 degree rating…Would much rather have the 32 degree bag since temperature usage will be around 40 degrees.Do not see means for exchanging bag?

Great bag for under 50 degrees, small and compact!
I used this for a summer camping trip where the nights were high 40s/low 50s. It was great for the cooler nights but I got a tad warm 55+. I do run warm at night though so could be a personal preference. SUPER light and easy to pack into a very small bag - perfect for travel!!
