The Sea to Summit Ultralight Self Inflating Sleeping Mat is light and packable for minimalist fast hikes.
The 2.6 R-value provides the insulation needed through the shoulder seasons while the memory foam means you don’t have to exert yourself inflating your mat at the end of the day. The Ultralight Self Inflating Sleeping Mat is the only mat in our S.I. range to come in an extra-small size, it’s easily fits into your ultra-light pack.
All of our S.I. mats use the first ever, multi-function single valve designed specifically for self-inflating mats. No more fighting re-inflation as you try to roll up your mat!

|30D POLYESTER TPU
The 30D polyester is a lightweight woven fabric with an extrusion TPU lamination and is used in our Self Inflating mats. The TPU lamination makes the fabric airtight and allows the PU foam inside our self inflating mats to be bonded to it.
|DELTA CORE-V TECHNOLOGY
Delta Core-V technology removes up to 20% of the weight and bulk of the polyurethane (PU) foam of a self-inflating mattress, while maintaining comfort and insulation. Our unique approach uses sophisticated pressure-mapping data to create 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 minimise the weight and packed size. Delta Core-V technology is used in our Ultralight SI and Camp mat SI models.
