Whether the altitude has you winded, or your lungs are having trouble keeping up with the fireside sing-along, give them a break and let the Exped Schnozzel PumpBag fill up your sleeping pad. Not only does this bag keep you from getting fatigued, its easy-to-use design reduces the moisture and bacteria that can build up inside the pad if you use your mouth. Besides, your mouth has better things to do, like break into a serenade to that cutie across the campfire--which is definitely not a move you'll ever regret.
