Everything about this sleeping bag is wonderful! It is very large, the material is really soft, and it is super warm. I love that it does not have nylon on the outside (too many sleeping bags have nylon exteriors, making them really noisy when you move around, not this one).
When you get this delivered, you right away realize how warm it is going to be because it weighs a lot, but that is ok, because you know it is going to be warm. Other sleeping bags are light, but are not always warm.
The interior is an odd color – gold – but is soft and cozy. It includes Velcro straps that cover the zipper pulls. It rolls up nicely into a carrying bag, that includes straps for easy transport and storage.
Can it fit two people comfortably? I can say that it would be very hot and uncomfortable for me and my wife to share this sleeping bag. I am sure that I will be using it by myself, because I will like the roominess.
It does unzip completely and can be used as two separate smaller sleeping bags, but these bags are for skinny people. I tried laying in one of the smaller sleeping bags, and it was too tight and uncomfortable. I think my tall, thin, 16-year-old son would fit just fine.
Overall, I really like this sleeping bag for cold camping, and I cannot wait to use it outdoors. It is a little expensive, but worth it!

The sleeping bag comes in the nicest carry bag that I’ve seen for sleeping bags (pic). It appears of the same material as the exterior of the sleeping bag (pic). The bag does have an odd configuration of straps whose main purpose seems to be to make the package as small as possible for transportation. The two straps that encircle the whole bag each have two slider adjustment buckles (pic), but no clips that let you easily move the straps out of the way of the bag’s opening (pic). So, you either squeeze the sleeping bag out around the crisscrossed straps, or you undo the slider buckles.
The stitching of the sleeping bag is clean and solid and the only loose threads to be found were in the carrying bag. The zippers are metal, but since a magnet won’t stick to them, I’m assuming they are aluminum. The black denim-like material is thick and well-constructed. The black color is a dark black. The interior fabric has a space age, hexagonal pattern to it. It feels slick but it also feels like it will stick to you if you are sweating. It has a very tight weave, and this should hold heat in extremely well – maybe too well if there are two bodies generating heat in this sleeping bag. Fortunately, each side has a zipper that can be pulled down to regulate internal warmth.
Laid flat on the ground it measures 54”x90” (or 72” for the top cover part). You must stretch it to make it reach the listed 57” width. For reference, a full-size mattress is 54”x75” and a queen-size mattress is 60”x80”. If you separate the two halves and make them into individual sleeping bags (pic), they measure about 27” wide. This is a workable size for kids or slender people, but several people in my camp group would not be able to sleep in the single person configuration. The filling used is good for insulation and heat retention, but it provides no cushion or support and if you place this sleeping bag on hard ground, you will feel the full impact of that hard ground, all night. This sleeping bag should work very well for the listed temperature ranges. Since my wife doesn’t like tent camping anymore, I will be using the full size of this on my full-size air mattress, and I look forward to being very comfortable in it.

I picked up this Double Sleeping Bag, it’s seriously awesome. First off, it feels super solid, like it’s not going to fall apart after a couple of trips. The high quality tough water resistant canvas shell is perfect for keeping out dampness, & the hollow synthetic insulation combined with the high tech graphene polyester pongee interior makes it insanely cozy. You can really tell it’s built for tough environmental conditions while still being extra comfortable. It locks in warmth & resists cold, so even on chilly nights you’re not shivering. I tucked inside of it on my back deck to test it out. The zipper is one of those premium YKK zippers, smooth, sturdy, no fumbling around in the dark trying to get out. Even though it’s a double sleeping bag, it’s not ridiculously bulky, so you can actually carry it around without feeling like you’re hauling a mattress. That makes it perfect for indoor use or tossing it in a tent for outdoor trips. I’m planning to use it at my friend’s lake house in the Finger Lakes in New York, & I can’t wait. Hopefully some chilly nights by the water, so I can really test just how warm it keeps me. I have a feeling it’s going to be ridiculously cozy. Even on warmer nights, I bet it’ll still be breathable enough that you don’t overheat. Seriously, this sleeping bag makes me want to plan a bunch of trips just to use it. It’s comfy, durable, & practical all at once. If you’re looking for an all season bag that can handle whatever Mother Nature throws at you, this one’s a no brainer for the cost. I’m already picturing a few nights under the stars at the lake with this thing.

It's very heavy and bulky. A nightmare to wash. It is warm but does not breathe like my other cold weather sleeping bag. It seems to retain moisture.

Large size sleeping bag for two, well made and comfortable. The fabric is good quality canvas on the outside and a silky, heat-reflective shiny fabric inside. Not only cozy and warm, but nicely padded to make the ground a tiny bit softer. Zips and unzips easily with large zippers and can be folded up easily to put in the included holder. The canvas case also has straps going around it in two directions, making for easy compaction and carrying.
