The MSR Nook Footprint provides protection from below, keeping your MSR Tent going strong, season after season. Made of water-resistant polyester-taffeta, the MSR Nook Footprint protects your Nook tent floor from sharp objects, such as rocks and pine needles, as well as from mud and ground water. It also increases the versatility of most MSR tents by acting as a ground cloth in lightweight tarp-style setups. Put your foot down and get the protection you deserve with the MSR Nook Footprint.
