Footprints are the ground protection beneath a tent. Exped's are the same size as the corresponding tent, but 2 in / 10 cm shorter to prevent water collecting between footprint and floor. A footprint protects a tent floor from abraison, dirt, water and sun. It also covers the vestibule floor space to protect the vestibule from dirt and humidity. Attaches with adjustable, elastic cords.
For Orion and Orion 3 tents, two seperate kinds of footprints.
