Hi all, call me crazy, but I'm planning to take a family backpacking overnight trip (as a trial run) with my husband and 2 kids. I have an OLD 3/4 length Thermarest that was a hand-me-down and I'd like to get another one that size, or similar, for our youngest to sleep on. Right now he's under a year old, so I'd like something that will last at least a few years, doesn't need to be super light weight, but needs to have a good R value. My almost 5 year will use the one we currently have or vise versa.
I can't find one anywhere! The only short one I found was a kid's EMS brand on Ebay for like $40 and $5 shipping, which isn't terrible if my kid will sleep ok on it. I'd even be ok with a round pet sleeping pad, but also can't find anything like that. I'd like it to be more like a thermarest's smooth surface (and durability) rather than the egg-crate UL designs just because I'm not sure how well they would sleep on something like that. Also, baby and 5 year old will be climbing/stomping on it most likely. I thought about a ridge-rest or a zrest, and maybe fold it in half, but they don't seem to have a great R value for warmth.
Any ideas? (We hit yard sales every Saturday in the spring/summer and have only ever seen one sleeping pad, which my husband bought for himself.)
