The Tatonka Floorsheet Tyvek is an ultra-lightweight tent footprint. It protects the tent floor from abrasion, dirt, moisture, and damage, and prevents the rise of condensing ground moisture in the vestibules. By placing your sleeping mat between the footprint and the tent floor, you can prevent your mat from slipping. What sets this tent footprint apart is the material – Tyvek may look similar to paper, but it offers entirely different performance. Tyvek is a hundred percent synthetic material made from high-density polyethylene fleece. It provides the properties of a thermoplastic, high-density plastic in a semi-solid state, preventing liquids from penetrating the surface. The fleece is lightweight, durable, breathable, and still offers high resistance to water, abrasion, bacterial penetration, and aging. Additionally, the material has high tear resistance and provides a robust, long-lasting protection. You can also trim the footprint to fit the area of your inner tent. With the Floorsheet Tyvek, you stay well protected on solid ground.
