Stone Glacier SkyAir ULT 1-Person Mesh Insert - The SkyAir ULT Mesh Liner converts this ultralight floorless tarp tent into a completely sealed and floored shelter， increasing its versatility as the weather changes or when camping in conditions where bugs are a concern. The Mesh Liner simply clips into the SkyAir ULT and only weighs 10 oz. ounces. If you plan to use your SkyAir ULT in a variety of conditions and into the later seasons， the Mesh Liner is an awesome piece to ensure comfort in an ultralight package.
