Product Reviews
- CKCarson K.Verified BuyerRated 5 out of 5 starsDec 30, 2022Awesome bag!
Great quality canvas bag and soft inside! Love that it can turn into a comforter and 2 separate sleeping bags. Getting it back in the bag was a challenge for one person, but easier with two people. The pup loves it too!
- SSWRated 1 out of 5 starsDec 8, 2022Good luck ever fitting it back in the bag
I just spent the last 20 min trying to stuff this thing back in the bag for the first time. Makes me never want to use it again. This will be the most frustrating part of your camping trip.
- JDJoseph Dello R.Verified BuyerRated 1 out of 5 starsNov 14, 2022Stitching is bottom quality.
Comfortable, warm, but the stitching on the canvas bag and the sleeping bag arrived frayed and weak. The canvas bag zippers ripped off after two uses.

- TPTeal P.Verified BuyerRated 4 out of 5 starsMay 8, 2024Cozy
I originally wanted a true canvas and flannel sleeping bag but as it cannot be found we bought this bag. It is warm and very cozy with bed sheet like interior. Love the baffles to keep around my shoulders, just think they could do without the drawstring. Too many cords, strings and Velcro can make sleeping uncomfortable. I personally don’t use the Velcro because I am zipping and unzipping at night whether it’s for temperature difference or helping kids stay in their bags so they seems superfluous to me and very loud in the middle of the night but I can see how they would be helpful to keep it from unzipping if you don’t want it to. My husband loved being able to stick his feet out at the bottom and I the side when too warm at the beginning of the night but get all tucked and cozy during the Coldest part of the morning. Have only slept in it with my husband (not alone) down to 40 degrees but some that felt colder with wind and humidity and have stayed very comfortable. I believe we would even to lower temps but have not tried yet. Would definitely buy again if we needed another or buy a similar single if needed.
- MCMichael C.Verified BuyerRated 5 out of 5 starsJan 24, 2024I love it.
Below zero outside, last log on the fire at around seven, and I'm good til morning.
- JPJason P.Verified BuyerRated 5 out of 5 starsDec 10, 2023Love this bag
Great bag. We love it. Have two now. Not too hot or cold. Cosy like a full mattress for two regular size people.
- JYJosephine Y.Verified BuyerRated 5 out of 5 starsNov 8, 2023Very cozy for car camping inside my van-turned-camper van!
Really wanted the experience of not making tons of noises while turning in bed with softer materials, and totally fine to sit on top of comfortably. Love the stickers that came with the bag too! Put it on my water bottle right away :)
- IPIsaac P.Verified BuyerRated 5 out of 5 starsJun 18, 2023Huge sleeper.
Haven’t used it but looking forward to it. I did in fact already buy my wife one she loves it. One thing is it really slippery if you stand on it. Just a observation. *** bless and good luck.
- RRRyan R.Verified ReviewerRated 1 out of 5 starsMay 24, 2023Bad stitching
The stitching on the canvas was bad right out of the bag and the stitching on the inside started to break within a week of owning. The stitching has only gotten worse soon there will be no stitching on the inside.

HUUUUUUGE!!!
So comfy, and was GREAT in some unexpectedly cold weather. Love the texture. Trying to get it back in the back is a mfing workout, lol. They have a video detailing how to get it back in the bag, but I discovered that a bit late and it's definitely just... Mostly in the bag until we take it out again.
