I have this. It inflates in 25 breaths; you'd have to be a big guy with a very deep breath to get it to inflate in the time they say. That being said.... it is by far the most comfortable pad I own. Love it.
overhereAs a gear junky who has to try *everything*, these blow up pads from Klymit are by far the easiest to blow up compared to other pads. Something about the V-shape design; it takes less air for the same comfort.
