Sea to Summit Comfort Light Insulated Sleeping Mat with Airstream Pumpsack - Regular - Green

The Comfort Light series bridges the gap between the Ultra-Light and Comfort Plus. STS have pared weight and bulk where they can be spared, and retained plushness where you'll appreciate it. Comfort Light mats are cut to the same tapered outline of the Ultra Light series and layered with Hybrid layer construction.

Hybrid construction consists of high cell resolution Dual Layer construction in the torso and medium-resolution Single Layer construction in the head and leg regions. All the layers are interconnected with the one multi-function valve. Hybrid construction gives high sensitivity and ground clearance where it's needed around the heavier torso and pelvis, and saves weight under the legs and head, where less sensitivity and insulation are required.

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.

• Comfort Light - Hybrid Layer Design - The Comfort Light range features dual layer construction in the torso for maximum comfort and insulation, and single layer construction in the head and legs where it's needed less.

• 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.
