Tumbl Trak Cheese Mat HIGH QUALITY - The Tumbl Trak Folding Incline is made out of all high quality materials. The interior foam is constructed of a PU base foam with a super strong EVA topper. Each mat has a durable 18oz knife coated vinyl cover; the best on the market! DONT BE FOOLED - Dont be fooled by imitation products that use cheaper foam which will break down after only a short period of use. SMART DESIGN - The lower half of the mat has a velcro on top, so when you fold the mat it attaches to the velcro flap on top side.
