This is my second BA Air Core pad. I bought the insulated version for colder weather camping. Guess what, it actually weighs slightly LESS than the regular version, at least on my digital scale. This pad is sooooo comfy at 2.5" and does a good job against the cold. It takes me between 17 and 20 breaths to blow it up. Kind of a pain but the good nights sleep is worth it. I'm a side sleeper and my hips are never sore anymore. The price, weight, packable size, and warmth of this pad simply cannot be beat.
As happy as I am with this pad I am disappointed that mine has apparently developed a leak after less than 14 bag nights. It's a very slow one and I can't hear any hissing, I think it might be a manufacturer defect at a seam. I'll be taking it back to the "other" gear store and getting a new one. Would have got five stars otherwise.
