I have 500 sq ft of mats from www.GETRUNG.com
. Had them for almost a year, and am getting ready to put in another order for more.
They are 1 inch thick, and very durable. Stay away from the red, as it tends to bleed on uniforms (blue and black has not). I recommend buying the storage sacks.
The prices are straight forward, unlike most other companies who hide fees. Feel free to PM me if you have need more details or info about them.
