Hi, my first post here
I've been hitting up the outdoor adventure store called REI, getting sleeping pads from them. A Thermarest NeoAir Xtherm (in regular size) retails for $180, easily wraps around your torso (done in the fitting room) and secured with an ace bandage. They sell fucking QUICK on eBay for $180, the large size sells for $260. There are many different brands, sizes, and types of sleeping pads and they're all super easy to get by wrapping them around your torso and wrapping yourself with an ace bandage. I've NEVER seen a security tag on any of them. I also use the ace bandage to wrap shirts around my calves (again, while in the fitting room) pretty regularly.
