The Sea to Summit Jet Stream Pump Sack is an efficient sleeping mattress pump, which doubles as a stuff sack. The pump works on a concertina action. Multiple one-way air intake ports inflates 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 onto mattress
• Roll top closure can be used as hand strap
• One-way air intake ports surround centre valve plug output
• Made from 30D Ultra-Sil®

Lots of air little effortBy: Penny Neuendorf on 15 January 2018I am very impressed with the amount of air that is transferred with each pump. I really like how little room it will take up in my back pack
SEA TO SUMMIT JET STREAM PUMP SACKBy: Dan hatfield on 20 August 2017It's a good pump. The connection to the mat is solid. It doesn't pop off like some pumps. It is a small pump so pumping up my comfort plus mat takes about 70 pumps. I can't comment on durability as I've only had it a couple of weeks and only used is 5 or 6 times. It doubles as a stuff sack but there's no way I'm getting my mat in it. It weighs next to nothing and goes easily inside my current mats stuff sack.
