The quality of the product is UNMATCHED! But my husband, like many men, have broad shoulders and muscular arms. . . . and the armholes in this vest were so tiny and constrictive that it rubbed him around the armholes, caused his shirts to look like poet shirts (a la Seinfeld), and we had to return it. :-( We were both super sad. I see on the photograph above that the armholes are still super small.
Please consider making them larger. My husband is a fit cyclist, he is not a heavy man by any stretch of the imagination (heck, the armholes were small on me and I do half ironmans!).
I am recommending this, however, for two reasons: 1. Customer service is awesome 2. if you have tiny arms, this will be AMAZING on you!
