TECHNICAL FEATURES

To make inflation and deflation of its air mats easier, Sea to Summit developed the multi-function valve. This valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort - all in one compact, low profile unit. It has also been designed to allow easy attachment of a pump, for simpler inflation.

Made of stainless steel with a silicone rubber grip, Pivot-Lock Handles are part of the superior engineering found in Sea to Summit’s range of Alpha Pots & Pans and Sigma Pots. In the pots, the handle rotates to secure the lid in place for transportation (no more lids rattling in your pack…) then swivels around to be secured in place with a one-hand operated thumb lock. This gives you the security to pick up even pots filled with hot food without the worry of the handle wobbling or becoming detached from the pot. In the pans, the handle swivels underneath the pan (away from the cooking surface), then swings back into place to be locked with an easy-to-use mechanism. You can flip pancakes to your heart’s content, knowing the handle will stay securely in place.

Air Sprung Cells™ are the core technology used in Sea to Summit Air Mats and are the reason you will sleep more comfortably on a Sea to Summit mat than on a conventional air pad. Inspired by the springs of a modern pocket sprung mattress, dozens of interconnected chambers (called Air Sprung Cells™) perfectly support your weight and conform to your body contours. The Ether Light range uses loops of TPU material to connect the top and bottom welds. This produces a thicker cell to give you a plush sleeping experience without compromising on Sea to Summit's Air Sprung Cell comfort.
