The Footprint is a custom ground tarp for the Mountain Hardwear Hammerhead 3 tent. Tough, waterproof tent footprints protect the floor from rocks, roots, twigs and other such ground hazards. Equipped with grommet tabs that attach to the tent pole, this footprint fits precisely one inch inside the tents perimeter so falling rain cant collect between the two.You can create a functional shelter by using just the fly, the tent poles, and this footprint. The resulting structure keeps off the rain, provides a fabric floor, and has tremendous ventilation at a fraction of the weight of the complete tent. The Pitch Light option is especially useful for fast-and-light, mild-weather trips.
