Don't believe the hype, lame idea poorly rendered
I bought this pad based on the previous reviews and a desire for a compact set up for ADV motorcycle trips. I didn't find it very warm at 30F in Colorado and it was sticky on my back in the warmer climate of the desert due to the pad only being separated from my skin by a layer of nylon. My BA mummy pad is insulated and stays put but the bag has very tight dimensions and was claustrophic.The Pad keeps you off the ground by about 2.5"s and creates an uncomfortable position for my arms. I fiddled with diferent pressures but never really got comfortable. You can't roll over in a mummy bag because it fits so tightly and you can't roll inside either. Its a miserable design. Oh yea and mine sprung a leak right away that I have yet to repair. If you decide to try the BA concept get a bag plenty big enough to roll around inside of it.
PS Stuffs the size of a quart thermos and is quite light.
PS it is quite compact and light, just not warm, comfortable or well made.
