This is a genuine US military surplus foam sleeping pad / bed roll. These mats measure approximately 75" x 24" x 3/8" and are constructed of a closed cell foam. They are great for all seasons but especially cold weather to insulate you from the cold ground.
Aside from using as a sleeping mat for camping, these also make great shooting mats, yoga mats, or any other time where you need to lie on the ground (such as working under a truck).
These sleeping mats have been previously used and issued by the US military and are in overall good condition still. They may have one or two straps, they may have nicks or small holes, but they have plenty of life left to give.
