Dot Drill Agility Pad
At 45 lb and 3/8" thick, this is the most durable dot drill pad you can buy.
Twice as thick and 3x as heavy as others so it will last for years. The dots are molded into the rubber (instead of printed) so they won't wear off. Improves quickness, reaction, and balance. Great for warming up. 4'L x 3'W. Instructional DVD runs 22 minutes.
