Sea to Summit Ether Light XT Insulated Mat Regular smoke

Air Sprung Cells™

The air sprung cells are the core technology of the STS Air Mat range, and are the reason why you will sleep better on the Sea To Summit Air Mats. Instead of the typical baffled construction, their Air mats are constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers called Air Sprung Cells™. Air Sprung Cells™ operate in the same way as a pocket spring mattress, as each cell deforms independently the mattress conforms to your body shape which feels softer and more comfortable with more body contact area and even dispersion of pressure.

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 fibers, 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. 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. The 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.

• Closed - compact low profile
• Inflate through one-way valve
• Press orange button to slowly release air to fine tune comfort
• Rapid air dump deflate port

40D Nylon face fabric

Sea To Summit developed the 40D ripstop nylon face fabric to hit the balance between weight and durability. On the inside we apply a bright white TPU to make the fabric airtight and weldable. On the outside we apply a thin PU coating to reduce the slipperiness of the surface, increase puncture strength and to aid puncture repair with selfadhesive patches.

Extrusion TPU lamination

The Sea To Summit TPU coating is applied through a process unique to the medical and aeronautical industries. Extrusion lamination is more durable, consistent and enables us to use our own TPU recipe. 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.

Sea To Summit has also introduced an anti-microbial treatment into the TPU to prevent mould or fungal growth inside the mattress. While they do have two superb pump options, the Airstream or Jet Stream, the anti-microbial treatment means you can go ultra-light and inflate with your breath.

Stuff sacks and repair kits

All Sea to Summit Air mats come with a quality stuff sack sized to suit your mat. We also include a small repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap. Stuff sack with integrated Airstream™ Pumpsack 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 our smaller 15mm mini multi-function valve, now featured on the updated Aeros pillow range.
