another pro nine chest protector question

[shipwreck]

Andy, I used mine for the first time last night at a HS scrimmage. I noticed that if I raised my arm from the side to a "hammer" position the flap stayed where it should. If the arm was raised more to the front a little, (sometimes my "hammer" is a little to the front, or like signalling an "infield fly", or on a "punch out", the little flap would come out from under the shoulder cap and stick out. I didn't think it looked very professional adjusting it back under all the time. Dave
