While all mats in the range are designed for year-round use, one stands out above the rest as an all season foam sleeping mat and that one is the Trekker Thermal 10 XL. What makes it different is that it is fitted with a metalised and embossed layer of polyethylene film to the upper surface which provides extra insulation and increases durability. It also provides a bigger surface area being two inches longer and two inches wider than a normal full-sized mat, to provide additional comfort. The mat rolls up small and light enough to be easily carried with restraining straps in a backpack, making it ideal for Guides and other youth groups.
