The OTV's I have found for sale claim that they only fit up to a 50 or 52 chest at best. I am 54 on a good day.

But it says it only fits up to a 47.
Honestly I just want a cheap vest for the time being. I don't want a super expensive piece of gear. That way I can upgrade later if I feel like continuing with the hobby.
