Here's what other sites are saying:
Keep the floor of your tent protected from sticks, sharp rocks, and other outdoor abrasives with the Easton Kilo Tent Footprint. You can also use it to turn your Kilo fly into a fast-pitch, ridiculously-lightweight shelter that will keep you dry but won't weigh you down.
Specialized tent footprints provide added protection against water, puncture, and abrasion. Use is recommended for all Easton tents to maximize performance and to prolong the life of the tent floor.
