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.

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. 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.

The innovative Women’s Delta Core™ system uses smaller cross-section horizontal Delta-shaped cores in the hip and foot areas to create extra-comfort / extra warmth zones in the Women’s Self Inflating mattresses. The coring technology creates extra support and insulation where women need it most. It reduces packed size and weight but leaves the top and bottom surface of the PU foam completely intact. This significantly improves the bonding of the foam to the shell fabric, which reduces the chance of delamination. The horizontal Women’s Delta Core™ technique is used in our Women’s Comfort Light SI and  Women’s Comfort Plus SI models.
