   At 32 degrees freezing & way below; the (hand size Velcro strap or whatever u wanna call it) at the left shoulder area; money can’t buy. It allows us to keep bag closed yet stick an entire arm/hand out. This is a rare unique major advantageous game changer in deadly hypothermia temps, & my primary reason for not buying other model’s. Theirs plenty of room for a pillow, & the pull cords to the right of our head allows for wonderful sealing around our face for heat retention & magnification/escalation. This bag & me are hottest when I’m nude since it magnifies body heat. Because “clothing” restricts/slows/hinders (body heat) from escaping into the bag where it can be magnified quickly. “Wearing clothes” is not your friend if/when you want to be warmer/hotter in this bag since this bag is so effective. But WOW getting NAKID in the ice & snow before getting into the bag makes me dance like a 64 year old Michael Jackson 🕺 with a shocked and dazed tallywhacker 🥒 wondering what in the heck fire is this fool doing to me 😳🤔

   Decided to add this 15 rated bag to my 40 rated bag for good measure. Roomy enough that I can slip this over my current bag for extra warmth when needed.

   Nice quality, well made, smooth zippers. Extra padding at the feet. Plenty of room for side sleepers. I love the top for when I want to tuck inside more. Hard to stuff back in its sack but whats new. Just have to squeeze/roll it then sit on it and strategically slide it back in. Did it without tooooo much effort. I imagine it will serve me for years to come.

   I took this Beautiful Coleman sleeping bag out of the box, it is massive but light when you carry it in your arms and inside it beautiful to be there and warm.
   It is very warm even with a tshirt inside.
   It is massive, enormous but I love it.
   I am 5ft6 and I like the sleeping bag big but colemandiscount.com product description says it can fit big and tall 6ft. 6 in. It is not too big for me.
   I know at least it will fit me or someone bigger and taller.
   I love the material and it seems to be of excellent quality, very well made.
   I could close the hood with ease once inside, I could feel the warmth even on my forehead.
   That is how warm it is.
   Personally I like the zip on this Coleman sleeping bag being on its left handside despite being righthanded.
   The zips do not catch, they are strong.
   I did not try to completely open the sleeping bag because I think in theory it could be done and then I would have a massive warm duvet as a cover. But I did not want to unzip it all completely and then find out I had difficulties zipping it back up again.
   The inside of the feet area is very warm and is red.
   I could fit the sleeping bag inside the bag it came in within 8 minutes I would say.
   The way I received it, is the hole width along its length was folded in half and then rolled inside the bag.
   So I copied that exactly.
   I folded the sleeping bag in half ie from left to right shoulder, then I rolled the sleeping bag from the feet area toward the hood, by pressing the sleeping bag as I rolled in towards the sofa.
   Then I put it under my right arm, but the biggest part ie where the hood was too big to put in first inside the bag.
   So I inserted the smaller side first and little by little pushed it in rolling the bag also.
   About midway I pulled in the remaining bag so that it would be tight on its end ( as I had difficulties pushing the rest of the sleeping bag in) and then it was easier to put the sleeping bag inside its bag.
   I am so happy with this sleeping bag. Warm. Of great quality. It is mine.

   So I bought this on a flash sale at $40 and thought it was a steal. This sleeping bag works but doesn’t at the same time. Let me explain. So it’s rated for 15 degrees Fahrenheit which is not the comfort level but the survival rating by ISO. I tested the bag out when it was 29 degrees out and it kept me warm until in the middle of the night my feet are frozen and it woke me up. It does have a zipper on the bottom that can be opened to let air in but that wasn’t open I checked and the insulation of the bag seemed distributed evenly so it wasn’t a light spot. The only thing I figured why I was cold was because I’m not a big guy, thus my body couldn’t heat the bag enough not to freeze my feet. That’s the only explanation I’ve got on why that happened and the only reason I had to return this bag. Otherwise this is a good bag and I would recommend it to any chubby people. When the is in the stuff sack it is pretty big. I bought this bag with a mummy bag rated for someone 6 foot tall and you can see how much bigger it is and why I assumed that my weight was the problem.

   Awesome bag, super long and big enough for me to move around in without getting tangled up. Kept me cozy and warm in a rainstorm with 5 degree C weather. I am 6 foot and with feet touching bottom was well over my head! It also has a great drawstring around head which also helped keep the warmth in. Overall very well constructed. It is a very large bag however, wouldn’t recommend for a hike in camping trip. It is slightly tapered at bottom which would help keep more warmth in. Didn’t notice till we got home that the bottom foot or so is flannel lined but rest is not as I used a liner. The zipper seems to be really heavy duty which is great. It does not completely unzip, but there is a zipper at the bottom of feet I guess for ventilation. No way I could get it back in bivy bag, but that’s not an issue. I keep it rolled with bungee straps anyway!

   I used this sleeping bag on a backpacking trip, which I don’t recommend you do, though I’m going to continue to do it, because I really like this sleeping bag. Coleman’s gear is more aimed at car camping than backpacking, and it shows as this thing is huge and heavy, taking up at least 20 liters compressed, if not more, and it doesn’t compress a lot. That’s also the point of the sleeping bag though. What it is advertised to do, it does extremely well, and this is the best sleeping bag I’ve ever used. I slept with out feeling constrained or having a lack of space to maneuver while I slept. I also slept in below freezing temperatures and became hot. You will not get cold in this thing. The hybrid style was also fantastic, as I could use it to hold my compression pillow in place and cover up my face should I get too cold. It has its down sides, but you can’t live in both worlds of a tiny light sleeping bag that is also big for big people and well insulated. You have to make a choice, and for me, I choose the Big Basin 15 from this point forward. I’ll gladly lug the thing.

   On our Northern Minnesota Sasquatch hunt over Memorial Day weekend at night it got down to 30 degrees. This sleeping bag out performed any others I had in the past. I bought two, my son loved his also. I am 6’3″ 250lbs my son 6′ 180lbs. I always sleep with socks on and a hoodie camping. But with the drawstrings closed it was toasty inside at 30 degrees. I had a foot exetra while inside (length and width) you could be 350lbs and 7 foot and be good with this bag. I was able to butterfly my legs inside the bag and that is a first. If you where going to use this winter camping 15/0 degrees maybe bring a fleece inside liner. The only draw back it was a little difficult re-stuffing it into the sleeping bag carrier. I just had to punch it in and lay on it to get the air out.

   Just the best night’s sleep you can have comma initially I tried to put it in its stuff sack by folding it and rolling it and that does not work you have to literally stuff it in the bag to get it in but what a fantastic night sleep, it’s awesome.

    I used these for a “camp in” at my son’s empty apartment on top of some air mattresses and they were great. Well made, good zippers. But I have not been out in the Yukon to really test them out (yet). But the Coleman brand has always been great. Not made in Wichita Kansas anymore (these are from China) but I am very satisfied with them.

    I’m 6’2″ 255lbs and needed a larger bag. As I reached 70 I feel the cold more, so I wanted a warmer bag. This bag meets those requirements well. I haven’t used it below 32f, but it’s toasty in the 40’s and above. I like the foot-box and the draft tube on the zipper. This is physically a large and heavy bag. I could barely remove it from the 40L stuff bag when new and won’t even try to stuff it back in. I purchased a 63L Compression Sack and it does fit. Great for Car Camping, NOT for backpacking.
