The Sea to Summit Jet Stream Pump Sack is an inovative sleeping mat pump for Sea to Summit mats. Resembling an accordian the Jet Stream inflates your mat using a concertina action. Multiple one-way air vales on the bottom allow the Jet Stream to fill with air while expands. These close when you push down on the sack, pushing the air through one valve into your mat.
Made from 30d Ultra-Sil the Jet Stream stores flat or can be used as a stuff sac for your mat or other gear.
