Solid safety covers that seal out all dirt, debris, and algae have long been hampered by their heavy weight, making them difficult to install and remove. Arctic Armor® Gold solid safety covers have solved this problem with a rugged new solid material – Vinyl Tuff™. This rugged reinforced vinyl material gives your pool the complete protection of a solid safety cover at 33% less weight. Not only is Vinyl Tuff™ lightweight and easy to use, it is also up to 35% stronger than standard solid safety cover material.
