Non-Slip Cargo & Trunk Liner. Made from durable, yet lightweight PVC and polyester, the Cargo & Trunk Liner features a leak/skid-resistant surface that assists in preventing items in the cargo area or trunk from shifting while driving. The liner can be trimmed to fit perfectly into the back of any vehicle and the generous 47″ x 47″ square size helps to keep the vehicle clean by protecting the carpeting and floor from dirt, grease and grime. Going to the grocery store? Use the liner to keep groceries and other items in place while driving. Going to the beach or the park? The liner will collect sand, water and other unwanted debris from cooler bottoms and chairs. Taking the dogs to the groomer or picking up plants and flowers? No problem. Simply remove the liner and shake it out, making clean-up a cinch.
