Footprint for the Laser Competition 1. Designed to prolong the life of your tent, this footprint will protect the bottom of your inner from sharp objects and dirt. It covers the bottom of the inner tent and the porch area. This can also be used with our 'fastpack' system, allowing you to use the footprint and flysheet without the inner. Although we are confident that our Waterbloc material will outperform any similar groundsheet fabric our footprints and groundsheet protectors offer some extra protection against sharp objects as well as keeping the tent underside clean.
