I purchased the medium sized vest based on recommendations and prior reviews (I am 5'-10", 176 lbs. and have a very athletic build -- e.g. no belly), and comments that said that it runs large. This is certainly not true. Maybe if I lose 10 more lbs., it will provide a better fit, but right now it is quite snug.
Just arrived, look great
EXCELLENT PRO QUIP AT GREAT PRICE.
Everything was good
