UltraLight Insulated Sleeping Mat

Air Sprung Cells™ technology: instead of the typical baffled construction, Sea to Summit™ mats are constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers that operate in the same way as a pocket spring mattress. As each cell deforms independently the mat conforms to the contours and movement of your body and feels softer and more comfortable with more body contact and even dispersal of pressure.

Sea to Summit developed the 30/40D Nylon face fabric to hit the balance between weight and durability. The 40D warp yarn (running lengthwise providing the fabric framework) adds strength while the 30D weft yarn (weaved across the warp yarn) reduces the overall weight of the fabric and creates a textured weave. On the inside they apply a bright white extrusion laminated TPU to make the fabric airtight and weldable. On the outside they apply a thin acrylic coating to reduce the slipperiness of the surface, increase puncture resistance and to aid puncture repair with self-adhesive patches.

Exkin Platinum® is a very lightweight, quiet, non-woven fabric that has a thin metalised layer applied to the surface that reflects radiant heat back to you.

THERMOLITE® insulation:is designed for ultimate performance and is made from specially engineered fibres to achieve a high CLO value with low weight. THERMOLITE® HL 1 high loft insulation is a fibrefill constructed with a unique 3D crimp of hollow-core and solid fibres which provide excellent lightweight warmth with superior durability. The THERMOLITE® lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the ground. Exkin Platinum® and THERMOLITE® are combined to great effect in this mat.

Liquid-Extruded TPU Lamination Process: An advanced lamination process which ensures an even and durable bond of the TPU (material which makes up the air bladder) to the face fabric. This process is superior to typical 'roll-to-roll' lamination and virtually eliminates the risk of delamination.

Multi-function valve: integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort, in one compact, low profile unit.
