The body shape depicted in the ads are real different for a 72 year old man w bad shoulders. The middle is to tight and the should to big, does do anything. Younger guys go for it.
I been using prop grade about month , feel really help you to protect you shoulder , only problems I have run very small .. so I recommend to use bigger size as you used.
I love the support this shirt provides. I am a very active 63 year old man and this shirt keeps me active as a 40 year old. I do wish it had a V-neck but I guess that might compromise the support that it provides.
