Took the bag to Chaco Canyon and it was in the mid-30s the second night. Bag was plenty warm. Quality construction, great zippers, easy to get in stuff sack.

    My son used this bag last summer on his first back packing trip to Colorado. Kept him warm and comfortable. Most nights were in the high 30's and we had no issues.

    I bought this bag for my kids after the cheap ones I bought first had major zipper problems. I bought one for myself recently after the same problem.

    So I'll first say the zippers work great. Strong and they don't snag much. I used the bag on a weekend campout. The temperature dropped to 30's first night and 27 degs (F) the next. I was warm in just underwear and wool sock. But I did use a 10 deg liner in the bag as well. But I've been in that type of weather in my old bag and had to have at least thermals on.

    For the price I got it after discounts ($77), it is a great buy. It comes with a compression and storage sack.

    Warmth: I have not yet taken my sleeping bag on the trail yet, however, I tested it at home when the outdoor temperatures where in the 20's. I used the sleeping bag on top of my bed (so plenty of insulation under me), was wearing long sleeved shirt, fleece bottoms and socks, and slept with my window open. Room temp was probably in the 30's. (Just a guess). The sleeping bag warmed up quickly, but never quite got me to the comfortable temp that made it so I could fall asleep easily. I ended up putting a light fleece blanket over my lower legs and did well after that. The cowling at the neck was fantastic!! I've never had that before in a sleeping bag and it completely changed the experience of moving about to get comfortable.... no cold air rushing into your sleeping bag!

    Sizing: As it turns out, size DOES matter. I purchased 2 sleeping bags, a regular length one and a women's size. I am 5'7" the regular is for me. The listing states that it will be appropriate for somebody up to 6' tall. No this is not true if you want to be comfortable. The length fits me just right, if I was any taller it would not be comfortable. As for the women's sized sleeping bag, the listing states that it will work for somebody up to 5'6" tall. I laid the 2 sleeping bags out next to each other and the women's is about 2-3" shorter than the regular sized sleeping bag, therefore, I feel that somebody 1" shorter than myself would not fit comfortably in it. Since I bought this as a gift for my 5'4" daughter, I feel that it will work great for her.

    While this is a nice bag, my husband isn't use to the mummy-type bags. I have nothing negative to say about it other than it didn't pack as small as we would need for trail riding/camping with horses. The pack weight is as advertised and the padding is nice too. We ended up sending it back and ordered a second Mountain Hardwear 20°F ExtraLamina Sleeping Bag - Synthetic, Semi-Rectangular due to its extra room and smaller pack size. (I have an extended review of that bag on Mountain Hardwear's page.)

    If your a serious backpacker, spend some more money and get a better one. Car camping it will do the job. It will not compress well for a backpack but would do for a day or two in the backcountry. Any longer than that and it will take up too much room.

  • “I am 5' 11" and 240# will this Kelty mummy style sleeping bag be uncomfortable for a man my size, in regards to being to confining in shoulder and waist areas. Also on the length for a 5 " 11" person, as I see this being near max for use ?”
    Asked by hungry_horse from Chippewa Pa on 10/7/2012 12:00:00 AM
    • The length is probably OK, the girth of the bag at shoulder is 62 inches around. If you measure around your shoulders and that measurement is 60 inches or more it may be so snug.
