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!

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.

Impressed for the price!
I am impressed with these sleeping bags. I bought 3 of the Mountaintop Hiking 600 32* for my children when they were $112/ea. I was looking for something that was well priced, lightweight, and warm enough for the backpacking we will be doing as a family. These fit my criteria, but didn’t have many reviews so I took a risk. I took my older 2 kids (7 and 9) camping this past weekend and I borrowed my youngest kids bag so I could test it out for myself. We had a 30* night and a 40* night. All three of us stayed warm and slept comfortably with proper clothing and sleeping pads. I am very happy with these purchases and will probably buy another one for myself!

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.

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!!

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?

Considero que fué una buena compra, dormí con 2 capas de ropa adicional para baja temperatura y no pasé frío, con otros productos he tenido mala experiencia
