A floor for your shelter.
You got the Twin Sister Shelter because you appreciate its lightweight compactness, and unfortunately a floorless design comes with that convenient lightness. So when you know the campsite is going to be wet and muddy, be sure to pack MSR's Twin Sister Footprint. MSR made it out of the same material used on the shelter, so you know you can rely on it when wet weather is in the forecast.
