This sturdy treated canvas tarp is the perfect footprint for your TETON Sports Canvas Tent or any other tent that needs a heavy-duty ground tarp. It will protect your tent from all manner of ground debris and adds a layer of protection from water. The 450 mm waterproofing keeps water where it belongs—outside of the tent. In addition to protection， the footprint keeps the bottom of the tent cleaner than using the tent alone. Less clean up while camping outdoors is always a good thing. Additionally， this footprint makes a great ground tarp for other outdoor activities. Use it as a picnic blanket， ground cover for resting during a hike， or as a sturdy beach blanket for the whole family. Its many functions will surprise you. Remember that all TETON Sports products come with the Lifetime Warranty， so your satisfaction is guaranteed!
