No additional protection is needed in the collarbone area of the BB2000. I don't know where he got that idea from. The BB2000 comes with a thermoplastic collarbone shield built right on there. I also have taken numerous shots in some pretty high level amateur baseball and not once have I even had a red spot under the BB2000.
In fact, I just checked the collarbone protector +POS sells. It says not required for use with the BB2000.
