Sea to Summit Ether Light XT Insulated Sleeping Mat with Airstream Pumpsack - Regular - Grey

Sea to Summit's lightest and thickest full size Air Sprung Cell (ASC) Mat with insulation for all-season comfort. Refining lightweight cold-climate sleeping comfort, this mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum and THERMOLITE insulation with a loop baffle Air Sprung Cell construction to create a 10cm thick mat with an incredibly low weight. 

Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall. Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.

• Includes an Airstream Pump that is integrated into the stuff sack for quick and easy inflation

• Extra Thick (XT) loop baffle Air Sprung Cells - Air Sprung Cells are the core technology behind the air mat range and are the reason you will
  sleep better on the STS air mats. Instead of the typical baffled construction, the air mats are constructed using a dot-weld pattern to create a high surface area matrix of interconnected chambers called Air Sprung Cells. Much like a pocket-spring mattress, as each Air Sprung Cell deforms independently, the mat conforms to your body shape which feels softer and more comfortable by maintaining more body contact area and even dispersion of pressure.

• Lightweight, quiet and grippy 30/40D Nylon fabric, field repairable with included self-adhesive patches
  

• Ultra-Fresh anti-microbial treatment to the TPU formula to prevent internal mould growth

• PillowLock attaches your Aeros pillow (sold separately) to your mat, holding it in place for a slip-free sleep. Easily secure your Aeros pillow to your Sea to Summit self-inflating or air sprung cell mat for a slip-free sleep. Designed to keep your pillow exactly where it’s meant to be, on your sleeping mat

• Thermal Insulation Technology - Exkin Platinum is a very lightweight, quiet non-woven fabric that has a thin metalised layer applied to the surface. Exkin Platinum thermal technology reflects radiant heat loss back to the user.

• Thermolite insulation, designed for ultimate performance, is made from specially engineered fibers to achieve a high CLO value with low weight. Thermolite HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibres, which provide 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

• Extrusion TPU lamination -  TPU coating is applied through a process unique to the medical and aeronautical industries. Extrusion lamination is more durable, consistent and enables STS to use their own TPU formula. It is vastly superior to roll-to-roll lamination, which is used in all other outdoor products at present and can suffer from delamination issues. STS have also introduced an anti-microbial treatment to the TPU formula to prevent mould or fungal growth inside the mattress. While STS do have two superb pump options, the Airstream and Jet Stream, the anti-microbial treatment means you can go ultra-light and inflate with your breath.

• Exkin Platinum and Thermolite are combined to great effect in each of the insulated versions of our mats.

• Multi-Function Valve - To make inflation and deflation easier Sea to Summit has developed the multi-function valve. Our 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 - all in one compact, low profile unit.

• Inflate and deflate pull tabs are tactile and colour coded for easy identification.

• 30/40D Nylon Fabric - 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 STS apply a bright white extrusion laminated TPU to make the fabric airtight and weldable. On the outside STS apply a thin acrylic coating to reduce the slipperiness of the surface, increase puncture resistance and to aid puncture repair with self-adhesive patches.

• The Airstream Pumpsack is now integrated in the base of the stuff sack included with every Air Sprung Cell sleeping mat. Harnessing the Bernoulli effect means the Airstream can be inflated with a single breath and fill a Sea to Summit air mat fast, with minimal breath condensation. Inverting the Pumpsack makes it compatible with the smaller 15mm mini multi-function valve, now featured on the updated Aeros pillow range.
  The new combined stuff sack Airstream Pumpsack weighs between 37g and 60g depending on the size and model of mat.

• Repair Kits - All Sea to Summit Air Sprung Cell mats include a small repair kit containing six self-adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.
