The NOMAD Darwin Duo 15.0 is a self-inflating sleeping mat for two people, designed for camping and guest accommodation, offering unparalleled sleep quality during outdoor activities. This dark gray mat features a generous thickness of 15 cm with high-density foam insulation and a mattress construction with vertical side walls that maximizes the usable sleeping area of 132 cm × 198 cm. The sleeping surface integrates a stretchable, body-conforming top layer made of durable polyester, providing excellent support and adapting to individual sleeping positions. The foam core contains horizontal air channels that reduce packing volume and weight while maintaining structural integrity, complemented by an antibacterial treatment that prevents mold growth. Two large multifunctional valves at each corner offer three operating modes: open for self-inflation, inflation for assisted pumping, and deflation for compact storage. The mat receives a PFC-free water-repellent treatment for weather resistance and includes a storage bag as well as a repair kit to address potential wear during extended use. This successor model from NOMAD Darwin maintains the brand's focus on practical outdoor solutions with attention to comfort, durability, and straightforward functionality.
