When it comes to tent longevity, we've got you covered. The Tracker(TM) 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 68D Polyester, it stands up to gravel and sharp surfaces that can take a toll on your tent. It packs small in an included breathable mesh pouch with a drawstring. *Nemo products are unavailable for purchase in Canada due to Canadian regulations.*
