ColemanBig Basin 15°F Big & Tall Sleeping Bag, Cold Weather Sleeping Bag with Snag-Free Zipper & Better Heat Retention, Machine Washable

For the price and performance, I don't think this sleeping bag can be beat, especially if you are looking for maximum warmth in severe cold camping conditions. The lining is very smooth and surprisingly comfortable, while also adding the benefit of providing a degree of water/weather resistance. Likewise, there is a generous amount of insulation that is fitted well in the sleeping bag so that it does not shift or clump up, keeping the whole bag evenly insulated.Other features such as the "zipper plow" make it a breeze to zip/unzip the bag which just further adds to how much value there is to this bag. The only "drawback" to this bag is that it is fairly large and bulky; if you are a backpack camper trying to find lightweight performance, this is not it. For my purposes though, this is basically perfect!

I was an Eagle Scout and we've used these bags a few times in temps down to freezing, and they work great if you get a fleece bag liner and put it in there. We were really nice and toasty warm.PROS:- HUGE - really really big. I'm 6ft and not small, and there's loads of extra room. If you don't like being cramped, look no further.- WARM - It's actually pretty darn warm on it's own.- GOOD ZIPPERS - they're on the left if you're laying in the bag, and they work well without getting caught a lot.- TWO ZIPPERS - One down the side and one on the bottom. Why is this good? Zippers tend to have issues going around corners, and this seems to help.- ZIPPER DRAFT TUBE - Huh? They made an extra...insulated tube of fabric next to the zippers running lengthwise that helps keep air out. And it's made of tougher material almost like a backpack which means...drum roll...the zipper finally doesn't get caught on the bag itself!!!- GOOD HOOD - The hood is really nice and roomy, like put a full size pillow in it roomy. If you sinch it up with the draw string you can have a face-size opening.- FLEECE FOOT - the inside bottom foot and a half has an extra layer of warm fleece.- BURROW - I like to kind of burrow down in a sleeping bag and there's so much room you can bend your legs, sleep on your side, have your arm curled under your head, and there's just so much room. I can put my fee at the very bottom and have the opening above my head.- LOOKS COOL - I know, it's a sleeping bag and how cool do you expect it to look, really? But it really does look pretty cool.CONS:- BIG - We put them in stuff sacks that sinch down and they're still pretty big bags.- NOT FOR BACKPACKING - like everyone says.HOW TO SLEEP WARMER:- Put an inexpensive and washable fleece liner inside the bag. There's plenty of room. It adds to the warmth significantly.- Change your clothes before you sleep. During the day your clothes get moisture from your own body heat. Change before you sleep and not only will you be warmer, having clean clothes inside the bag makes it stay cleaner.- Don't over-dress. Start off in like shorts and a t-shirt, no socks, and you'll be warm without sweating. If you start off too warm, you'll build up heat, sweat, and then be colder.- Put your extra layers down in the foot. Got a sweatshirt you'll probably wear in the morning? Shove it down in the foot. There's room, and it'll be warm when you're ready for it in the morning.- Wear a beanie, helps with heat loss on your head if you stick your head out for fresh air.FLEECE LINER:We used something like this (though not this exact one) and it gets even warmer.https://www.amazon.com/Stansport-Fleece-Sleeping-Bag-Red/dp/B002YXITMW/ref=sr_1_7?dchild=1&keywords=fleece+sleeping+bag+liner&qid=1592870476&sr=8-7STUFF SACK:We used a compression stuff sack like this and were able to fit the sleeping bag and the fleece liner in it together.https://www.amazon.com/Lewis-N-Clark-Compression-Drawstring/dp/B079JRVVD1/ref=sr_1_4?dchild=1&keywords=lewis+n.+clark+compression+sack&qid=1592870350&sr=8-4

Would buy it again, it’s comfortable and huge. I can wear clothes when I’m inside the bag and move around without the bag clinging to me. It’s not small for backpacking I use it in my vehicle. It’s rated as 15 degree bag but weather sometimes was 0 degrees and was still comfortable and warm with a few extra layers on me.I love the color too the inside and outside.I I tried rolling it but it’s pretty thick . I definitely recommend it I bought three different sleeping bags I returned 2, I kept the third one which was rated at 30 degrees I might need it in the future when it warms up. So the fourth which is this one COLEMAN is AMAZING.

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.

Addendum:Slept in this bag in 14°F snowy weather (inside a tent). I warmed the bag up with 2 Nalgene’s filled with hot water before I climbed in. I had what I mentioned below along with this sleeping bag plus I had another blankets on top (car camping). I was comfy that night. The next night got down to 25°F and I was too hot. I had to remove a Nalgene and get out of the fleece liner plus vented the bag a few times. This bag is excellent for the price, I think.Original review:I’m 5’7”, 245# and this bag was nice and big with plenty of leg room, something necessary for someone with RLS.I put everything at the bottom of my sleeping bag and on the side next to me to keep them from freezing (electronics, shoes, drinks, etc). I was amazed that my shoes were cool but not frozen in the morning considering they were at the very bottom of the bag furthest from me.I slept in this bag in 29°f weather and was toasty warm. I had on a t-shirt, long pants (90% cotton, 10% polyester), and a fluffy polyester bed jacket from Walmart. No socks. I wore a hat and some UV protection gloves for hikers with no finger tips. After the bag warmed up, I was toasty comfy, even a little too hot at times and had to take my hat off and bring an arm out of the bag from time to time for short periods.Also, I initially was in a fleece sleeping bag liner but wound up crawling out of it after a while because I was too hot. It did help get me warmed up though because the bag was quite cool when I first crawled in.And I did have an insulated inflatable mattress underneath me as well.Only issue I had with this sleeping bag was the zipper. It was a little rough zipping up in some spots while inside if it.The bag is heavy. It’s good for car camping but not for hiking.
