The Ultra Light Range consists of a single layer construction of medium resolution (making it the lightest Sea to Summit sleeping mat with the smallest packing volume yet the comfort of the Sea to Summit Air Sprung Cells).
Air Sprung Cells
Air Sprung Cells are the core technology of the Sea to Summit sleeping mat range. Instead of a typical partition wall construction, Sea to Summit sleeping mats are provided with a spot-welded construction of interconnected chambers that form a large-area matrix. These chambers are called "Air Sprung Cells". They function like pocket spring mattresses with each chamber deforming independently so that the mattress can adapt to the shape of the body. This construction makes the mats softer and more comfortable, provides a larger body contact area and balanced pressure distribution.
Extrusion TPU lamination
The TPU coating is applied in a special way that was previously used exclusively in the medical and aviation industry. In addition, an antimicrobial treatment was integrated into the TPU to prevent mould inside the mat.
A 40D ripstop nylon material has been developed for the surfaces of the mats, which offers the ideal mix of weight and durability. Light, white TPU is attached to the inside, making the material airtight and weldable. A thin PU film is applied to the outside to make the surface non-slip, to protect it against pinching and to make repairs with self-adhesive patches easier
