   If you need plenty of room in your sleeping bag, this bag is a bit restrictive but beautifully made and good for up to 6 footers.

   Tested out a couple weeks ago where temp was just at 20°F. I’m a cold sleeper and I felt a slight chill at feet and legs, but warm everywhere else. I’m 6’3″, wide shoulders, and size is plenty. With a little more preparedness in clothes layering I think I would have fared much better. One annoyance was the Velcro flap for top of zipper. Had to really fuss during the night reaching around to free it from it’s anchor point and pull over zipper to keep it from unzipping, which is it’s purpose and performed fine after all the fussing. Personally don’t think the extra strip of Velcro to keep the flap out of the way is even necessary. I ended up putting a blank strip of Velcro over with non lock side out so I don’t have to release the flap each time I want to place it over the zipper. Otherwise very pleased with the bag, especially the roominess and ability to turn without the whole bag moving with you.

   I’m 6″2 and weight 300 lbs. I am going to hike the AT trail in three years and I want to be prepared for cold weather. Most sleeping bag ratings are rated for survival conditions, meaning that you will survive but won’t be warm and toasty. I got the 0 Degree bag, so I’d have a good chance at being to sleep comfortably when it’s 20 degrees out. Coleman advertises this bag as “big and tall.” It is neither. I could not fit into it to save my life. Don’t say big and tall and then send me a bag that is neither. It’s hard enough for me to find a cold weather sleeping that fits me.

   I know this Coleman Sleeping Bag is geared towards tall individuals. However, we found that it also works decently well for my 6′ husband and small child to fit. Either side by side or feet to feet using the bottom portion that is designed to unzip to cool your feet (see picture). It also could work for two children under 10 yrs to fit feet to feet. For recreational camping, it’s pretty nice. It’s still a mummy bag, but it’s spacious. There’s a little pocket on the inside for you to keep a cell phones utility tools, or a small flashlight. Anything you would to keep nearby and know where it is. There were a handful of loose strings. A concern only if the bag starts unthreading and let’s the down out. The biggest con for us is the zipper, it catches on the sleeping bag even though there is black canvas lining designed to keep it from doing that. It actually stuffs back in the storage bag really easily and quickly. The reinforced straps in the storage bag are a nice feature.

   Zipping this closed in my living room for the first time after receiving the package, and the zipper jammed up, lost grip on one side, and can’t be reset. I didn’t even know zippers could be one time use.

   Coleman used to be a name to be trusted in camping gear. Tents are garbage that blow over and leak, and now I guess I can add sleeping bags to the mix. The temp ratings are basically lies. This thing has near zero stuffing. When they say 4C they should say “you will survive but not be comfy”. Also I am 6’3″ and they claim this thing is long enough for a person 6.5 feet tall. Yeah ok. Also not very roomy. I legit own an colemandiscount.com brand of sleeping bag that says 10C and it is thicker, more roomy, and warmer than this thing. I think Coleman just outsources production now.

   I should also mention the zipper – inside where there is supposed to be a thick piece of material to keep out drafts, that doesn’t even line up along the entire zipper. I tried it inside my place and could feel air freely moving inside the sleeping bag from outside through the zipper.

   This is way too much money to spend on outsourced junk with a namebrand slapped on it. Will be returning, and I think I am done buying Coleman anything – disappointed life-long camper.

   Nice well-built, well designed sleeping bag for warmer weather. Nicely proportioned and roomy.

    This is a big bag that packs small. Not as small as a down bag, but still much smaller than a cheaper, basic bag. It’s plenty spacious for taller people. The zipper design is clever so that you can open up the foot area. The phone holder is too small for today’s bigger phones, but I don’t think I would use that anyway. The mummy-ness of the bag is not as mummy-like as nicer bags. If you want a mummy design without too much claustrophobia, this might be good for you. The design of the packing bag is a little odd. The way the straps work is unlike any I’ve seen before. Overall, though, it’s a nice bag with some unique features that still has some room for improvements.

    Amazing sleeping bag. Size; I brought XL & being 5’8″/185lbs I have plenty of room to twist / turn. Warmth; no heat in RV, 22 degrees for a few days & never felt chill inside the bag. Climb in the bag at 9:30pm & comfortable until 7am wakeup. I must have read reviews for 50 sleeping bag, extremely happy with this purchase.

    Thought it’d be great but the inner lining feels to plastic & uncomfortable, & it’s too heavy to carry around. No for me tho.
    

14. Matthew eastman Verified Buyer – 6 June 2025

    Very comfy and not to tight. Kept me very warm in 4C weather I think I could sleep in -5C with thermals on. Very nice insulated foot box. I recommend this

    I really liked this bag. Its a great size, fit me perfectly (6’0, 170lbs) and I was so so so comfortable in it. My only qualm with it was its weight and size since I wanted a backpacking bag. Otherwise this one did the trick, would recommend.
