Sea To Summit Air Stream Pumpsack

The Air Stream is our big-volume sleeping mattress pump, it is based on
our 20L Ultra-Sil® Nano dry sack, with added valve plug and foot loop.
Using the venturi effect means the 20 litre Air Stream can be inflated
with a single breath. Two to three cycles from the Air Stream are enough
to fill Sea to Summit Sleeping mats, meaning you’re ready to go quickly,
with minimal breath condensation in your mat, or dizziness from blowing
the mat up. The Air Stream can be used as a 20L dry sack, or as a vacuum
bag to store your down sleeping bag.

Inflates most sleeping mats in only two or three breaths
