The women's-specific Ether Light XT Insulated Sleeping Mat combines Exkin Platinum® and an extrra thick THERMOLITE® insulation layer with quiet, lightweight and grippy fabric and 10cm-high Air Sprung Cells™ for comfort in colder conditions. Other features include a multi-functional valve for easy inflation, deflation and fine tuning, an Airstream™ pump integrated into the stuff sack for quick inflation and the PillowLock™ system to hold your Sea to Summit pillow in place. The extra height of the mat makes it ideal for side sleepers so your hip stays off the ground during your sleep.

Features

  • Updated R-value and weight
  • Women's-specific: shape is wider from hip to knee and narrower at the shoulder and a thicker THERMOLITE® layer for exttra warmth
  • Air Sprung Cells™ conform to your body shape, providing a more even dispersion of pressure across the mat for a more comfortable night's sleep
  • Extra thick (XT) loop baffle Air Sprung Cells™: larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with the 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.
  • Lightweight, quiet and grippy 30/40D Nylon fabric, field repairable with included self-adhesive patches
  • 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 you.
  • The THERMOLITE® insulation lofts up inside the Air Sprung Cells to prevent convective heat loss from your warm body to the cold ground
  • Ultra-Fresh® anti-microbial treatment is added to the TPU formula to prevent internal mould growth
  • Multi-functional, high flow-rate valve provides fast inflate, deflate and easy fine-tuning for personalised comfort
  • PillowLock™ attaches your new-generation Sea to Summit® pillow to your mat, holding it in place for a slip-free sleep
  • Includes an Airstream™ Pump that is integrated into the stuff sack for quick and easy inflation

Technologies

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. Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with the 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.

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: 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 recipe. It is vastly superior to roll-to-roll lamination, which is used in a lot of other outdoor products at present and can suffer from delamination issues. STS have also introduced an anti-microbial treatment into the TPU to prevent mould or fungal growth.

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, all in one compact, low profile unit.
