Therm-a-Rest NeoAir AirTap Pump Kit

The featherweight Therm-a-Rest AirTrap Pump Kit converts any air-tight bag into an efficient, quick-inflating pump. Pierce one of the included plastic bags, a garbage liner, or a plastic grocery bag with the tip and attach the valve coupler. Then, all you have to do is capture air in the open end of the bag, roll it down, and force all of that air into your mattress. You can even use a stuff sack to create a permanent pump system.
