That's a SYNMAT 7 LT, made by Expedition Equipment. It's the best thing since sliced bread. I think of all the years that I slept on a half inch thick, quarter in thick on walls, I cringe.
This pad blows up to 2.5 inches, it weighs 2 pounds and packs so small you put it inside your pack. I should do a write up on it. A little pricy, around 100+. Travel in luxury Steve.
