The Jet Stream Pumpsack is a versatile, easy to use and ultralight mattress pump that also doubles as a stuff sack.
Sea to Summit says:
The Jet Stream is our efficient sleeping mattress pump, which doubles as a stuff sack. The pump works on a concertina action. Multiple one-way air intake ports inflate the pump quickly on the upstroke. On the down stroke, this air is expelled into the mattress through the centre valve plug. Each stroke delivers more than a lung-full of air, without making the user dizzy or adding moisture into the mat. The Jet Stream stores small and flat, or can be used as a stuff sack for your sleeping mattress or other gear.
The Jet Stream Pumpsack is a sleeping mattress pump which also doubles as a stuff sack. It's easy to use as a mattress pump, all you need to do is connect the pump to the valve on the mattress, use the roll top loop as a handle, pull to draw the air in and then push to inflate. It takes quite a few pumps to inflate a mat though and the tube gets a bit rowdy when you compress it, but after a while your mat is inflated!
The pump sack also doubles as a handy stuff sack which will fit most air bed type sleeping mats. Say good bye to feeling dizzy and hello to Pumpsack, your new camping buddy!
