The NEMO Dragonfly 1P Footprint lets us extend the life our one-person Dragonfly tent by protecting its thin floor from punctures and abrasions. This tarp features an abrasion-resistant polyester ripstop fabric that protects our tent floor from rough or rocky ground--plus PU coating for waterproof protection. The footprint is perfectly sized to fit just inside the perimeter of the tent to prevent water from tunneling underneath in wet weather. That's added piece of mind to protect our investment in a quality, NEMO tent.
