Bought a Kevlar lined shirt from here, sizing is far smaller than they say. I chose a large from there measurements and I’m 6’2” 89kgs, it fits my father that is 5’7” and 65kgs. Then no refund as I admitted I had worn it, on a 10 minute ride mind you. Either buy two sizes larger than you normally would or even buy a more reputable brand in my opinion.
