Offering additional protection for rugged or wet terrain, the Telos Bigfoot Footprint adds a waterproof fabric layer under the tub floor and vestibule of your tent. Protecting the tent floor and keeping your gear dry and off the ground, the Telos Bigfoot Footprint is made of 68 denier polyester, with circular-bartacked Hypalon attachment points. A Telos Bigfoot Footprint also makes Dry Set-up and Take-Down a breeze and allows for an easy Fly Only tent set-up for ultralight adventures.
