Sizing guidelines off
I really like the vest. It’s not too bulky and works well in the agility ring. For me, the sizing instructions were off. I am an older women, 5’4”, 155 lbs. I measured between a large and extra large. I ordered the competition vest from Arrak in a large and it was way too big. It was more vest than I wanted also. I returned that vest and bought this vest I a medium. It fits perfectly. I usually wear the vest over a t-shirt.
