Sea to Summit Ultralight ASC Insulated Mat Regular Single Person Mattress - Orange

Single person mattress in orange for a comfortable rest in a tent or hammock. Great for longer outdoor expeditions, camping, canoeing or multi-day cycle routes.

Durable 40D nylon, air chambers, Pillow Lock system

The design utilises 181 interconnected Air Sprung Cells, which mould to the wearer's body shape for improved support and comfort. An inner layer made of flexible and durable thermoplastic polyurethane (TPU) with an antibacterial coating protects against the growth of mould and fungi inside the chambers. The outer layer is made of 40D nylon reinforced with a Rip-Stop structure to prevent tearing. The polyurethane coating gives non-slip properties and allows easy repair with self-adhesive patches. The PillowLock system keeps the pillow in one place, preventing it from shifting during sleep.

THERMOLITE insulation, Exkin Platinum technology, easy pumping

The mattress features Thermolite HL-1 insulation, made from lightweight synthetic fibres that provide good thermal protection at a low weight. The Exkin Platinum technology used reflects heat back to the user, improving the mattress' insulating efficiency.

The large valve allows quick and easy inflation, as well as adjusting the amount of air, allowing you to adjust the firmness to your individual preferences. Thanks to its one-way action, it prevents unintentional air release. For complete deflation, simply open the valve.
