X Vest Sizing Help

I cannot find any stores near me that stock X Vests to go try one on, so I’m turning to you guys for help. My waist is about a 33-34, which kind of puts me between sizes (M and L). I’m pretty short, and while my waist is moderately sized, I’ve got a barrel chested build and big shoulders and upper back - my ribs stick out near my diaphragm. I’m 5’5" and currently sitting at 185 and 12% bodyfat.

I’m leaning toward ordering the large 40lbs. vest as I think it will fit my chest and back the best, but I worry about it moving around and not being snug enough around my lower torso. The medium has the opposite problem and might constrict my breathing.

Any advice suggestions?
Thanks in advance.
