Piranha Gear Cloth Ankle Guard We designed these for doing most stand up styles of combat martial arts like MMA, Muay Thai, Karate, UFC, etc. Machine washable - though the running them through the dryer a lot will kind of cook them after a while Maybe that "air drying" thing would be a good idea instead of the machine? Sold in pairs because most people usually end up wanting TWO so we thought that would be a totally cool way to sell them
