All sizes seen on the site are not direct conversions. Top Rank has to convert the European sizing as well as the different sizing systems from each country. The size conversion process can be an arduous task, nevertheless Top Ranks conversion system is 99.99%. This can be as simple as subtracting or adding a certain number to the size and we get the exact American measurements.
In some cases, some European sizing is so detailed that it would be an inventory nightmare to figure out the exact conversions down to the centimeter. Top Rank does its best to get it good enough were if an item is short on the sleeve long, Top Rank acknowledges that one may have to get a slight alteration on that item with full knowledge that it would still qualify for the size we’ve converted it to. Top Rank will not convert an item knowing that it cannot be slightly altered because of a person’s arm reach is too short or too long.
