The Sea to Summit Comfort Light Insulated Sleeping Mat is a hybrid mat with an innovative and practical design. It has a double layer of Air Sprung Cells™ for optimal comfort and insulation where you need it, and a single layer of cells in lighter areas to minimise weight and packing size.This clever design features Exkin® Platinum fabric that reflects your body heat back to you, and Thermolite® insulation that prevents heat loss to ensure a warm and comfortable night’s sleep every time. The Sea to Summit Comfort Light Insulated Sleeping Mat comes equipped with everything you need to keep your sleeping mat in tip top order. It has a spare one-way silicone valve flap and a repair kit containing six self-adhesive repair patches. There’s also an anti-microbial treatment to ensure no problems will arise from warm, moist air becoming trapped inside the Comfort Light sleeping mat.
