The Footprint Advance Pro 2 brand's MSR is a groundsheet specially designed to protect the floor of your tent.
This protective mat is cut to the exact dimensions of your tent Advance Pro 2. It protects your tent’s integrated groundsheet (whether sewn-in, detachable or zipped) from tearing and keeps it clean if you’re camping on damp ground. This groundsheet will significantly reduce condensation inside the tent and insulateyou from the cold ground. It must be completely covered by your tent to prevent any water from getting in.
