ALPS Mountaineering footprints are a great addition to any tent purchase. They are cut a little smaller than the dimension of the tent floor and have corner attachments, which help keep it in place. Simple, fast, and all at a great price. Made from recycled polyester, the Felis Footprints are a great addition to the ALPS Mountaineering Felis Tent. Sizes are specially made to coordinate with your tent, and attach with buckles at each corner.
