Sea To Summit Air Stream Pump Sack

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 sleeping mats in only two or three breaths
• Oval base design
• Fully seam sealed with sealable valve plug
• Made from lightweight 15D UltraSil®
