Product description
Sea to Summit Air Stream Pump Sack orange (orange)
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 vaccum bag to store your down sleeping bag.
Ultra-Sil
Ultra-Sil is a very light waterproof nylon fabric. The outer shell is surrounded by a silicone layer; the inner layer is PU coated.
