      Can’t Say Enough!

      It feels so good to crawl into this bag at the end of a long, cold day. I’ve shared it with a partner and I’ve used it solo in temps between 15F and 40F and it is so comfortable and cozy. It is bulky and heavy and I’m obviously not taking it on the trail, but it is perfect for my car. The liner is so soft and feels good on bare skin-yes-you can sleep in it with minimal dress if you want and you’ll still stay warm. I love this thing and am very happy I have it. I did get a zip up protective duvet for it because 1. the shell is kinda loud when you move around and the duvet helps dampen the noise, and 2. it will only fit in large industrial washers at a laundromat-and probably have to be in 2 pieces so I want to keep it as clean as possible.

      Warm & thick!

      This bag is the first sleeping bag we have used where I didn't get cold. It is perfectly puffy and cozy. I know others have mentioned they are unable to re-stuff it but after watching the YouTube video on how to, we've had no issues stuffing it away. The Mammoth is cloud-like...we love it. Excellent customer service as well.

      Best bag ever!!!!

      My bf and I have used this bag approximately 7 years and it is awesome! Extremely warm and comfy. Will never use another brand- our favorite!! We also have a Summer season bag also perfect! Buy one - you won't be sorry! Also, stuffing into bag does take some patience and strength. I take my time and can do it in a boutique 10 mins. Watch the video :-)

      Great purchase

      Soooo warm and cozy. The sleeping bag is very large and difficult to fit back in sleeping bag cover, but other than that it’s fantastic.

      I like it a lot.

      I have various other bags that I use for camping and backpacking etc. , but I don't have a huge bag that I can spread out in for an afternoon nap in my day bed. This one fills the bill. I keep both sides unzipped so I can ventilate if it gets too warm. Its very comfy. I slide into the bag and listen to a podcast for an hour......and doze off, or not. Life is good

      not bad for $85

      I am a vanlifer and use this bag. Nice quality. It does NOT unzip into 2 halves though and as far as cold temperatures if it gets near freezing I must put a fleece blanket inside. Below freezing requires another fleece on top of it. The rating of 0 degrees must be for Celsius.
