Thanks for suggesting Gossamer Gear, I hadn't heard of them before. After checking out their website, I think that's who I'll be buying from. I'm either going to get the nightlight torso length or the thinlight 1/8". One's $9, one's $18. Both are way cheaper than the pads I was considering from REI, not too mention way lighter, and even with the shipping costs, they're not much more expensive than the pad from walmart and these are American made. I'm sure walmart's pad is probably made in China.
