Wilson Platinum Chest Protector

This CP fits nicely and is very comfortable.  The only drawback initially was that the stock harness can cause it to sag a bit.  Once I bought the All-Star Delta Flex harness, the CP now stays put all day long and is even more comfortable as a result. Nice and snug.  I've been hit numerous times, and have never felt any pain, so it protects beautifully.

I use this as my primary CP and have for the last 6-7 years and have no regrets. It has excellent protection. That's not to say you will not feel when you get hit, b/c I've been hit by some nasty fouls and it has hurt like a SOB, but I shudder to think what it would have been with anything less.

I'll be in the market for a new CP in the next year or 2 and will shop around, but this will be at the top of my list.

I have worn this CP for the past 3 seasons.  I must say that from a protection standpoint, it's second to none.  I have taken numerous pitches and foul balls directly to the chest and shoulders with no ill-effects.  I tell people that I hear them, but, I don't feel them.  I will say, however, that the bulkiness of the CP makes it difficult to pull on and take off your jersey.  But, that's a small price to pay for security. 

I wear a size L on both base shirts and plate, and I use the Platinum. An XL for me would look as though I'm setting sail  so that's out.

One way to put on your shirt is to put both arms into the sleeves, then pull the shirt over your head; sometimes it's a bit of a wrestle to get the shirt over the shoulder pads, but not always.
