Product Info

When you give it everything you got and the mountain gives nothing back, at least you know you'll get a good night's sleep. The Sea to Summit Ultralight Self Inflating Sleeping Pad lets you recharge and do it all again the next day. This pad is super light for fast and efficient trekking, and when you've spent your last breath on the climb, you won't have to think about using any on this pad.

Product Details


30D Woven Polyester with Anti-slip Print


Delta Core-V Technology FoamIn 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.

Women's Delta Core TechnologyThe 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.


Thickness1" / 2.5 cm


SI Multi-function ValveA 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.

Women's Specific ShapeNarrower in the shoulders, wider in the hips and knees. Offers greater comfort no matter what position you sleep in, and perfectly matches Sea to Summit women's sleeping bags.
