The OG Jim Bradley Speedball  is made to ground and pound! Hence the name, gym bag.
 
Currently, offering a black and red 5x8 and a solid red 6x9, as pictured above.
 
Made out of durable, italian cowhide leather, nylon loops and stitched rivets. This handmade ball needs to be tested to be believed. 
 
Tip: To inflate ball you need to disengage the lock on the zip with a piece of wire (paperclip will do) We suggest filling to 2.5 to 3.5 PSI.
 
We DO NOT recommend filling up above 4 PSI on 5x8 or the 6x9!
