The Flatmat is 28 inches wide x 66 inches long x 1/2 inch thick. Light enough for easy traveling, yet lay flat for use. 1/2" thick high density closed cell pad inside for extra protection from the ground. Large tough grip rubber pad insures that you have a stable shooting platform that is so vital to top scores. The though grip rubber is a light color so you won't be laying on a hot black piece of rubber during those warm summer days. The cover is a tough fast drying canvas upper with a water proof bottom. It folds up in thirds and has an attached handle for easy carrying. Weighs about 4 pounds.
