The Outwell Dreamboat Single 12.0 cm Self-Inflating Mat features the Outwell® FHF (Flat High-Flow) valve, providing improved airflow for both inflation and deflation. Its vertical side static fabric panels resist bending under pressure, making inflation easier with less effort. This mat offers unique heat-regulating foam construction for optimal comfort year-round, extra-large foam cavities for superior comfort while reducing packed size and weight, and a 3D shape with a deep profile for ultimate comfort. It is made from ultra-durable stretch polyester with soft-on-skin technology and has delamination-proof TPU construction for exceptional durability. The static side fabric improves the 3D shape and aids easier inflation. This is a PFC-free design for eco-friendliness.
