User Review: Ozark Trail Sleeping Bag
Fill: 3.5 lbs polyester
Temperature Rating: 40 degrees F
Weight: about 5 lbs
Price Paid: $15
I used this bag from February of 2002 to June of 2002 on the Appalachian Trail, and I still have it. The first night out it was less than 14 degrees F, and I had at least 50 nights under 40 degrees F. I can't say I was warm, but I wasn't shivering, freezing, or cold either, although I did wear 2 layers of clothing. I won't ever buy an expensive sleeping bag after carrying this cheapo, unless I can find a cheap bag that weighs a lot less.
I think the expensive bags are just marketing and overengineering, unless you are going to the arctic. You can buy an expensive bag if you think it will make you more hardcore, but I will gladly tell everyone how hardcore you are if you pay me to do so.
