Prevent water from seeping through and dirt from sullying your tent???s bottom with this footprint. Aligning right with Big Agnes??? Copper Spur HV UL3 model, it adds a layer below the shelter???s floor to guard against abrasion, roots, punctures, and debris. . Note: Normally when you purchase a tent footprint you only need to consider 3 things: make, model, and size. For example, make=Big Agnes, model=Copper Spur, and size=2-person. However, with Big Agnes tents there's a 4th factor, HV (high volume) or non-HV. Big Agnes Copper Spur HV UL tents are 2 shorter than Big Agnes UL tents. In other words, not all Copper Spur 2-person footprints are the same size. Double check whether or not your Copper Spur is HV and purchase the correct footprint so you're ready for your next adventure. . . .
