Sea to Summit Ultralight Insulated Sleeping Mat

Sea to Summit sleeping mats provide exceptional comfort due to their Air Sprung Cell design. Instead of using baffles like many other mats Sea to Summit use dot welds to create a high surface area matrix of interconnected chambers. This design allows the mattress to work in the same way as pocket sprung mattresses. Each cell is able to deform independently allowing the mat to more accurately conform to your body shape for superior comfort with a softer feel and fewer pressure points

The Ultralight Insulated Mat has a single layer of medium resolution cells to give you the lightest and smallest pack-volume mattress without compromising on comfort. A layer of Exkin Platinum, a quiet non-woven fabric reflects radiant heat loss back to the user. The mat's cells are filled with Thermolite insulation preventing convective heat loss between your body and the ground.

The Ultralight  Insulated Mat features Sea to Summit's Multi-function Valve which can be used for easy inflation, pressure adjustment and rapid deflation. This design means there's no need for multiple bulky valves.

The Ultralight  Insulated Mat is constructed from a 40D Nylon face fabric with a TPU lamination on the inside making it airtight and weldable.. The fabric offers an excellent balance between weight and durability. To the outside of the face fabric they apply a thin coating to make the surface a little more grippy, increase puncture strength and make it easier to repair with self-adhesive patches

The lamination process between face fabric and the TPU layer is known as extrusion TPU lamination and is used for medical and aeronautical applications. Compared to roll-to-roll lamination, used in all other outdoor products at present, extrusion TPU lamination is more consistent and durable.

The TPU used in Sea to Summit Mats has an anti-microbial treatment to prevent mould or fungal growth in the mattress making it possible to inflate these mats with your breath.
