The Exped Down Mat XP 9 Sleeping Pad is an insulated sleeping pad for expeditions into winter-cold temps down to -36.4°F. You can certainly pump in air direct from your lungs, but this pad comes included with a Schnozzel Pumpbag, so you should probably save your breath and it'll be ready for sleeping in about 2 minutes. Bonus, the pumpbag is also a waterproof stuff sack, so when the adventure is over or you're moving camp, the whole pad can be tucked away and into your pack. Sleep well, 3.5" off the ground and 700 fill power goose down hidden within the baffles.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
