Big Agnes Footprint for Copper Spur HV Ultra Light and HV mtnGLO Tents, 5 Person

Although it still makes me crazy that footprints aren't included with tents it's worth the money. Growing up my family always brought a garden variety tarp along on backpacking trips to use under our tents but this footprint fits exactly under the tent instead of sticking out or having to cut down a tarp to fit (and then dealing with the fraying) and weighs no more than a song. I also love that we can fold it up with the tent and still have it all fit in the tent bag.
