Sea to Summit Ultralight ASC Insulated Sleeping Mat - Regular - Orange

At Sea to Summit we set out to design a mat that was better than what was already available. ‘Better’ is of course a very subjective ambition: while we could have made the lightest, or the most compact mat ever designed, we ultimately went back to why we carry a sleeping mattress into the wild in the first place — to give us a better night’s sleep. We’re really proud to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping!

Features:

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

• Air Sprung Cells - Air Sprung Cells are the core technology of our sleeping mat range, and are the reason why you will sleep better on a Sea to Summit sleeping mat. Instead of the typical baffled construction, Sea to Summit sleeping 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. This makes for a softer and more comfortable feel with more body contact area and even dispersion of pressure.

• Single Layer Design - The Ultra Light range has a single layer of medium resolution cells to give you the lightest and smallest pack-volume mat without compromising on Sea to Summit’s Air Sprung Cell comfort.

• Thermal Insulation Technology - Exkin Platinum is a very lightweight, quiet non-woven fabric that has a thin metalized 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. 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.

• 40D Nylon Face Fabric - STS developed the 40D ripstop nylon face fabric to hit the right balance between weight and durability. On the inside they apply a bright white TPU to make the fabric airtight and weldable. On the outside they apply a thin proprietary coating to reduce the slipperiness of the surface, increase puncture with self-adhesive patches.

• 20D Nylon Internal Fabric - We also developed a lightweight 20D nylon laminated with TPU on both surfaces to create a strong double sided weldable fabric. This is used for the interior of our double layer, offset Air Sprung Cell mats.

• Extrusion TPU Lamination - STS 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 outdoor products at present and are prone to delamination issues.

• STS have two superb pump options, the Jetstream and the Airstream. However, for those weight-conscious users who will inflate the mats by mouth, the antimicrobial treatment in the TPU will prevent issues caused by warm, moist expelled breath trapped inside the mat.

• Stuff Sacks and Repair Kits - All Sea to Summit sleeping 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.

Q. HOW DO I REPAIR MY AIR SPRUNG CELL MAT?

A. Every mattress comes with a repair kit containing a number of patches. These self-adhesive repair patches can be used on holes up to about 2 mm in diameter with complete confidence. If you have a hold larger than this, please contact STS enquiries as to the best way to effect a repair.

Q. WHAT DO I DO IF WATER OR MOISTURE GETS TRAPPED INSIDE MY MATTRESS?

A. Having a small amount of moisture trapped inside your mattress is not a major issue, and the moisture will not damage your mat in anyway because of the anti-microbial TPU lining. You should, however, give your mattress an opportunity to dry out when you get a chance. The best way to achieve this is to hang the mat in a warm and dry environment with the valve open.

Q. WHAT’S THE BEST WAY TO CLEAN MY STS MATTRESS?

A. Mild soap and water is the best way to try and clean any dirt or grime off your mattress. The external coating on the face fabric will ensure that cleaning is quick and effective. Be careful not to use any strong cleaning products or bleaches, as these will damage the fabrics and potentially compromise the integrity of the mattress.
