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).
Exkin Platinum is a super light, noiseless material with a thin metallic surface. Exkin Platinum Thermal Technology reflects heat radiation back to the user.
Thermolite insulation, designed for ultimate performance, is made of special fibres that provide a high CLO value at low weight. Thermolite HL-1 High Loft insulation is a textile fibre filling of unique 3D frills with solid and hollow core fibres that combine outstanding, light heat with excellent durability. The Thermolite insulation spreads within the Air Jump Cells to prevent convection heat loss from the warm body to the floor. To achieve the best possible effect, a combination of Exkin Platinum and Thermolite is used in all versions of the insulated sleeping mats.
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.
