Calling all minimal packers! Not sure you want a self inflating mat because you're concerned about packing ultralight? This one has alternating foam and air channels inside so the mat stays really lightweight and packs down small. You get a mattress that self inflates almost entirely (just add a few breaths at the end) to a comfortable 2" (5cm) thickness that feels amazingly comfortable. And no need for pumps or hyperventilation. Includes stuff sack.
