Camp Self-Inflating Sleeping Mat

Delta Core-V­™

In our lighter SI air mat models, we have removed 20% of the weight and bulk of the PU foam by using our vertical Delta Core-V™ method. We use sophisticated pressure mapping data that becomes the blueprint for our distinctive graduated core pattern.

Where extra warmth and support is needed for the body contact areas - shoulders, hips, and feet - the core holes are smaller. In the less critical areas, we have removed more foam to minimize the weight and packed size. Delta Core-V™ technology is used in our Ultra Light SI and Camp Mat SI models.

SI Multi-Function Valve

We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.

Extrusion Lamination

Extrusion lamination is common in the medical and aeronautical industries, but Sea to Summit pioneered its use in outdoor products. Liquid Thermoplastic Urethane is applied to the face fabric through an extrusion head, where it bonds permanently. The result: Sea to Summit sleeping mats are more reliable and longer-lasting.
