The Sea to Summit Jet Stream Pump Sack is an efficient sleeping mat pump that also doubles up as a stuff sack.
Working on a concertina action, the Jet Stream Pump Sack has multiple one-way air intake ports that 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.
Lightweight TPU base has finger loops to hold pump on to mattress
Roll top closure can be used as hand strap
One-way air intake ports surround centre valve plug output
