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

  • Inflates most Sea to Summit sleeping mats in only two or three compressions.
  • Fully seam sealed with valve plug.
  • Packs down extremely small, but its in-use volume of 20 Liters is perfect for storing clothes or a sleeping bag inside your pack.
