Used this sleeping bag for the first time in the catskills the first week in August. It says it's rated for 35 - 60 degree weather, but it wasn't below 50 and I was freezing. The sheet that they say you can remove, is not removeable. It is sewn into the left side and has toggle clasps on the right side to hold it in place. You can unzip both sides and remove the top of the bag and just use the sheet if you want.
Also, because both sides do unzip, there is approx. a 3 inch gap at the foot of the sleeping bag where the two zippers fail to come together.(If you look really close at the picture above you can see a small bulge at the foot of the bag, that's where the gap is.) All I kept thinking all night was, "is something going to crawl in and touch my feet". I don't understand why they wouldn't at least try to overlap the zippers, who in thier right mind wants an opening at the foot of thier sleeping bag. It also felt a lot thinner than I would have expected for a name brand. I had a cheap walmart brand bag that came free with my old tent that was fluffier than this.
Now for the pros: First I love the colors. It's a nice light olive green and dark charcoal grey. I also love the hood on it. It definitely helped keep the heat in around my head and neck. The stuff sack it comes in is really cool. It has a cinch sak and then another piece that caps it and clips on. Helps to keep it clean and dry. Also, I love the pocket on the outside top of the hood. I was able to put a mini flashlight in it, just in case I had to get up in the dark, there would be no searching for a light.
Overall though, I was dissappointed. I love the concept of the bag with a hood, zip pocket, and stuff sak, but the actual item fails to live up to the description. Especially the hole at the bottom and the non-removeable sheet. After being cold at night it would have been nice to know I could replace the cotton sheet with a flannel one, but no. Not sure yet if I will return this or just buy a new one and use the bottom layer of this one to add more cushioning and take advantage of the hood.
