Gun Safe Covers are designed to provide protection from dust and debris and to keep your safe concealed from sight. The gun safe cover is constructed of a lightweight, breathable material that will not trap moisture. As you can see here, this material is plenty tough and will provide you with years of use. Liberty's Safe covers are designed to be used for indoor use only. If your safe is in the garage, as long as it is out of direct sunlight, it will work there as well. Direct sunlight will cause fading and discoloration.
