My 15 year old son is shooting up a mile a minute, but he's scrawny. Today, he is 6ft and 1/2" He weighs 140. Has a small chest in girth, but looong. I do not know how big he will get, but it seems he has a few years left to grow and fill out. He will be umping 14 yr old games now, and is moving up in levels each year. He says getting hit in his soft shell protector hurts, of course. I want to get him a good protector that he's not swimming in, but that will allow him to grow some more. I'm thinking WV, but could be persuaded otherwise. I am clueless about what size, or which style to buy. Help please? I have read all of the other posts regarding CPs.
