Thank you for your question. I would say that the intent of softball and baseball catcher's equipment is alike: to protect the catcher, but there are a few differences. The biggest may be with the softball chest protector, where I have seen additional padding to protect the female softball player for obvious reasons. The other thing that is different will be the length of the shin guards, given men are generally taller. The helmet, mask, knee protectors should all be pretty much the same. I have seen the knee protectors (the pads catchers where so that they can lean back and "sit" versus squat the whole time) used more by the softball catcher than the baseball catcher, but that can go either way.
