The models in the Dreamhaven series are equipped with the Outwell FHF Valve (Flat High-Flow Valve) - a flat valve that guarantees high airflow during both inflation and deflation. The sleeping mats not only offer outstanding performance at a good price but also impress with top-notch comfort thanks to their 3-D shape with a deep profile. The 3-D profile is supported by textile side walls that do not bend under pressure. This means less air needs to be supplied, making inflation easier. Weight and pack size are further reduced by the horizontal air channels. The carrying bag with shoulder strap ensures hassle-free storage and effortless transport.
