This is the NeoAir Xlite, a lightweight sleeping pad from Thermarest. The size is regular. I purchased it quite some time ago, but I recall using it only 5 times. I haven't been able to go tent camping in a while, so I'd like to pass it on to someone who can use it. It's a very lightweight, compact, and warm sleeping pad. The crinkling sound is a bit noticeable, but I think its performance more than makes up for it. There are almost no visible stains. I've also confirmed there are no punctures. However, please consider that this is a used item when making your decision. I have lost the repair kit. Only the sleeping pad itself and the stuff sack are included in this listing.
