40D Nylon Face Fabric

Exkin Platinum Fabric and Thermolite

Thermolite HL-1 – HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground.

Small – 66" x 21.5" x 2.5

Regular – 72" x 21.5" x 2.5"

Large – 79" x 25" x 2.5"

Extrusion Laminate – Extrusion lamination is common in the medical and aeronautical industries, but Sea to Summit pioneered its use in outdoor products. Liquid Thermoplastic Urethane is applied to the face fabric through an extrusion head, where it bonds permanently. The result: Sea to Summit sleeping mats are more reliable and longer-lasting.

Hybrid Layer Air Sprung Cells – Inspired by the hundreds of springs found in a modern pocket sprung mattress, the hundreds of small interconnected chambers (called Air Sprung Cells™) perfectly support your weight and conform to your body contours. The Comfort Light series of mats has an internal layer of 40 D Nylon in the torso section. This allows the welds of the lower and upper cells to be offset, resulting in a greater number of cells in this area for greater support and insulation. The cells in the head and leg sections of the mat do not have this internal layer, which saves overall weight. This hybrid construction (two different weld patterns) may be the perfect option for an end user looking for more comfort and insulation without adding to much weight.

Integrated Airstream Pumpsack – The Airstream™ Pumpsack is Sea to Summit's big volume mattress pump. The clever design opens at one end to stow the air mat and the other end unfolds to become the built-in pump. The Airstream™ Pumpsack can be inflated with a single breath and takes just two or three cycles to fill the mat. Not only is it faster than inflation by mouth, but there is minimal breath condensation entering the mat and it eliminates dizziness from blowing the mat up directly by mouth.

Includes – Quality stuff sack which doubles as a pump, a repair kit containing six self-adhesive patches for repairing punctures in the field, and two spare silicone one-way valve inserts.

Multi-function Valve for Fast and Easy Inflation, Deflation and Fine Tuning of Air Pressure

Anti-Microbial Treatment Added to TPU Lamination – To prevent delamination/mold issues caused by moist air trapped inside the mat.
