Sea to Summit Air Stream Pump Sack
The Sea to Summit Air Stream Pump Sack is an ingenious high-volume pump for your Sea to Summit inflatable mattress. Essentially the 20L Ultra-Sil® Nano Dry Sack but with a valve and foot loop the Sea to Summit Air Stream Pump Sack not only doubles as a dry sack, it’s ultra light, easy to pack and even easier to use. Just attach it to your mattress valve and inflate it by unclipping the top, and blowing into it from a distance of about 30cm. This will inflate the sack using the Venturi effect. Then close the sack and push the air into the mattress – it even has a foot hold to keep it in place while you’re pumping. This genius device can fill your mattress in two to three breaths and is definitely worth packing if you’re moving camp grounds regularly.
