I have the Big Agnes Two Track 1.5'. It is high quality, It rolls up nice and compact, It has its own stuff sack and comes with a repair kit. (What more could you ask for?).I recently used this pad when I went car camping a few weeks ago. It was comfortable and kept me warm. It got down to around 40 degrees at night. The top is lightly textured to limit slippage. The pad will slide around on the tent bottom it you really toss and turn, but if you don't move too much you will be fine.Only suggestion: If your space allows, go for the 2 in or thicker (for X-tra comfort).
I have had this for many years and it has never let me down. It does not inflate very much however it is enough. The main purpose of one of these is not for comfort but to keep yourself from losing heat to the ground. It performs both functions so in my book its a good buy.
I'm a big fan of the big agnes two track. For the most part it's a self-inlatable pad, but to get it pumped up to the extent you want you may have to put a little extra in yourself. I've used it outdoors a couple times so far, and am preparing to go on a 5 week backpacking trip through the Northwest so hopefully I'll have some more feedback then. I love the 'stuff sack' it comes with. You don't have to deflate it completely in order for it to fit and the velcro straps make it easy to strap onto a pack.I'm about 5'11 and the regular fits just fine. Really comfortable pad.
