Like CPR for your air mattress, a few compressions of this portable air-beam frame pad pump will easily inflate your air-filled sleeping pad without leaving you dizzy and out-of-breath. Store it rolled up with your pad or keep it stashed in the fist-sized nylon stuff sack. Also extends the life of your sleeping pad by keeping out unwanted moisture from old-school huffing and puffing. A smart tool to rescue a good nights sleep. 2.2 oz.
