Teton Celsius XXL Cold Weather Sleeping Bag for Adults & Kids - 20F to 35F Extreme Temperature Rating - Lightweight & Water-Resistant for Camping, Hiking & Backpacking - Includes Compression Sack for Easy Storage

...I am in my mid-60's and still love to camp, but due to a replacement-hip and several damaged disks in my spine, sleeping on the ground in a tent is no longer a comfortable option for me, so for the last decade I have slept in my Dodge-Minivan on a regular mattress...But this has worn out, so I decided to upgrade......I wanted a cot, but didnt like the small, creaky, uncomfortable cots carried in most stores, so went online and found a GInormous one that had good reviews, and the manufacturer also made a sleeping-bag in the same size...40 x 85.....I bought both, and coupled them with a 2" memory-foam pad which I sandwiched between the bag and cot with an old quilt, holding that combo in place with light elastic cords......I am just sorry i did not do this years earlier!..This bag is HUGE!!!...It is very comfortable, with two-drawstring closures around the top to keep out drafts, very nice large padded batting along the zipper so you never make contact with the zipper while inside the bag, which also insulates that area well.......It has two nylon loops on the bottom for tying down to a cot to keep the bag in place, which is a nice feature...and overall the craftsmanship looks solid and of good-quality materials...I have had expensive down and synthetic bags in the past, and this bag compares nicely with them at a modest price making it good-value for your bucks!...I have not tested it to 0 degrees, but I can say that at 40 degrees I had to open the zip and hang my arms out for a long time as it was Very warm inside, so I am extremely happy and satisfied with this bag so far!...Obviously, only repeated use and time will tell how well it holds up and performs in the long run, but seriously, at this price, if it only lasted a few years it would have been well worth the reasonable price......This bag also comes with a very sturdy and well-made stuff-sack that has multiple compression straps to shrink it quite small...but it is fairly heavy...so I doubt this would be a good bag for back-packing...but I seriously doubt it was designed for that purpose in the first place...and if you are vehicle or tent camping, the weight is hardly a factor......My only complaint is minor, as you get a choice of left or right-hand zipper, and this bag can be joined to another, which would create a combined bag the size of a king-sized bed!..JEEZ!....I chose the left-hand zip, but when it arrived..the zip was on the right-side as I laid in it, but was still labeled left-hand zip..So I found this a bit confusing, as I guess if you were standing at the foot of the bag the zip would BE on the left....but once in it...it is on the right-side of the bag?...Perhaps this is a normal way of designating sides, but should be considered when you place an order......Aside from that, I am Very pleased with this product, and would gladly recommend it and the manufacturer at any time!...The bag arrived well-packed and boxed, and in a short time after I placed the order....and I cant wait to go out and do some serious camping with it!
