This air mattress is very compact when deflated, and it fits inside in a 4-liter drybag with enough room to spare. While I must give it credit for being relatively puncture proof, this air mattress is far from perfect. My biggest complaint about it is that it does not deform to my body shape when I lay on it, and consequently it is uncomfortable to sleep on, especially on the side, but at least it's better than the bare floor.
The Youtube video below from Justin Outdoors does a good job explaining the features, both the good and bad parts, of the Therm-a-Rest NeoAir Xlite Ultralight Air Mattress
