Featuring the Multimat valve system, you can simply twist the valves on the mat to inflate and deflate it quickly and easily. With 20kg/m3 PU foam core, the camping mat will be inflated and ready to use in a jiffy! The TPU membrane around the air-tight seal helps the sleeping mat to maintain its flexibility at the same time as keeping water out. Able to put up with light showers, the 150D outer polyester fabric is water-repellent as well.The mat comes complete with a stuff sack for easy storage, and a straightforward repair kit if ever needed, which will save you buying a new one right away.Despite being a full length, the Trekker 25 is still surprisingly pliant and easy to pack into rucksacks and holdalls.Multimat valve system - self-inflatingFull-lengthTough 150D polyester top and base fabric - water-repellentTPU membrane for air-tight seal - keeps water outQuality high insulation/rebound 20kg/m3 PU foam core - fast inflationComponent temperature tolerance: -20oC to +50oCIncluded: Stuff sack, retaining bands, repair kitSize: 1830x510x25mm (L)Weight: 890gTog Value: 5.3Compactness: 270x150mm (mid-folded)Colour: Blue
