I bought the long version. Its big, bigger than I need (I'm only 6ft). But quite comfortable. Rolls up quickly and easily(not sure about the review that said it takes 15 minutes to get the air out, it squeezes right out when you roll it up). I have a Therm-a-rest Ridge Rest for lightweight camping, but this is great for car camping, canoeing, short hikes to camping, etc... If the regular size was available I would have gotten that. Make sure this will fit in your tent, it doesn't fit in my 2 man tent(74x74) but two fit quite well in my 3 man tent(90x60).
