I absolutely LOVE this vest and it fits perfectly !!! I vary between 100 to 105 lbs; 5’3 1/2 - I purchased a (M) after speaking with Mark by phone with having him help me with the measurements, very polite and helpful ! (Thank you Mark) I wear laced all the way up with reg shirt, but with heavier shirts &/ or my leather jacket underneath I can let out laces and wear it fine! It’s soft and broke in yet heavy enough it’s tough; it’s also lined. It packs my armor inside the very nicely too.. I would highly recommend.
