Hi all. I bought a BA insulated Aircore a few years ago. I spent 2 nights on the Manistee River trail and both where cold and hard....I went home and did the test BA suggested to find a hole. What I found was about a dozen holes the bottom 6" of mattress, top and bottom side. I called BA and they sent me a new one. Guess what? I took it out Friday night for a one-nighter to test some new equipment I "gained" over the winter......I slept on the cold, hard ground yet once again with the new one. I went back home and performed the same test. The same holes in the same areas appeared. Im very angry and almost done using anything that requires air. Im tempted to purchase another 3/8" thick closed cell and make a 1" thick bed roll combined with my 5/8" thick.

Few things to know:

1. I use a 5/8 foam pad under it for ground protection
2. I sleep in bare feet
3. First time was in my 40 deg Kelty bag, this time it was my 15 degree Rocky Peak bag.
