Champro Sports 16\” Chicago Style Softball Chicago-style softball – It was created during the 1920’s using an over-sized 16\” softball. Over time the ball became soft and squishy, so everyone in town – rich or poor – could play the game in the streets without using a baseball mitt. That famous over sized softball became known as a \”Chicago-Style Softball\” or \”MushBall\”. Champro’s Chicago-Stye 16\” softball is constructed with the same durable 100% cowhide leather cover, Kapok core and unique hand-stitched seams which gives this softball its unusual look. The seams are hidden behind the interlocking cover, making this softball more durable – ideal for use on rough playgrounds, grass and asphalt. These over sized 16\” circumference softballs are designed for limited flight and will get softer after some use. Priced for one 16\” softball. Item # CSB-16
