Sizing is way off - Ultimate Direction Jurek FKT Vest

I haven't had a chance to use this yet because I had to exchange it and don't have the new one yet. Just gave it 3 stars rating since that was the midpoint. Will edit once I have used it.

The sizing is not close to the description. I have a 34" waist and ordered the medium since it said said it should fit up to a 41" waist. I was worrried when I ordered that it would be too big. However, I had to loosen the straps all the way in order to fasten it. That was wearing a thin t-shirt. I don't know if I would have been able to fasten it at all with a sweatshirt or jacket on.

My chest and waist aren't the same size, but I don't have a huge chest either. For reference, I used a tape measure and found that at the bottom of my rib cage I am 39". For a suit jacket I wear a 42". I would say for sizing you should pretend the sizing chart says "chest size" instead of "waist size". Or order the same size of t-shirt you would order and ignore the size chart. I'm thinking the large will be a perfect fit for me.
