Save your tent's ass by using the Big Agnes Slide Mountain SL2 Tent Footprint. This nylon rip-stop ground cloth prevents rocks and sticks from puncturing your tent floor, adds another barrier to moisture in wet weather, and can be used in conjunction with just your fly and poles for a lightweight, minimalist shelter.
Big Agnes footprints protect the bottom of your tent or shelter from wear and tear and provide an extra barrier against sticks, stones and dirt. The Slide Mountain 2 Footprint was designed specifically for the Big Agnes Slide Mountain 2 Tent.
Use this coated nylon taffeta footprint underneath your Slide Mountain 2 SL tent to protect floor from wear and abrasion. It's sized slightly smaller than the tent's footprint so that it prevents pooling of water under tent during wet weather. Footprint will add approximately 13 oz. to your pack depending on tent model. SL = Super Light.
