When it comes to tent longevity, Nemo has you covered. The Dragonfly footprint is not for waterproofness; Nemo floors already are impenetrable to water. Rather, it protects your tent floor when camping on rough surfaces, adding longevity to your tent. Made of 75D PU polyester, it stands up to gravelly and sharp surfaces that can take a toll on your tent. It packs small in an included breathable mesh pouch with a drawstring. 75D PU polyester taffeta is durable and resists wear from sharp and gravelly surfaces. Waterproof to keep the bottom of your tent from getting wet and dirty. Attaches securely to Dragonfly Bikepack with grommets to perimeter points. Sized to fit underneath tent without being visible. Included mesh bag with drawstring for storage and transport. Season 3 Minimum Weight 0 lb , 5.4 oz / 154 g Dimensions 35 x 88 in / 89 x 224 cm
