Sea to Summit Camp Rectangular Self Inflating Sleeping Pad

Delta Core-V Technology Foam: In lighter SI air mat models, Sea to Summit removed 20% of the weight and bulk of the PU foam by using a vertical Delta Core-V™ method. They use sophisticated pressure mapping data that becomes the blueprint for their 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, they've removed more foam to minimize the weight and packed size. Delta Core-V™ technology is used in Ultra Light SI and Camp Mat SI models.

Wide: 72" x 25" x 1.5"

Large: 78" x 25" x 1.5"

SI Multi-function Valve: A new twist on Sea to Summit's multi-function valve that 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. The "one-way" inflation valve can 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 in air mattresses and pillows.

Extrusion Laminate: 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.

Pillow Lock System: The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019). Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics. All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.
