Due to the fact that the two layers can be pressurized independently, the top layer can be inflated to your personal comfort, while maintaining a high-pressure base layer for protection from the rough or uneven terrain. Both layers can be adjusted independently using the fine tune valve to get just the right level of softness and support.
We use Exkin Platinum®, a quiet non-woven fabric, to reflect radiant heat back to the user and Thermolite®insulation to prevent convective heat loss between your body and the ground. All Sea to Summit air sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve insert.
