Hi Everyone--

Hoping some of you can help me figure out jersey sizing. I recently won a state championship and they use voler for their jerseys- due to the custom nature, they don't accept returns. I've never bought with voler before, so I want to make sure I get the right size. I have bought through pactimo and giordiana before, both of which I have small jerseys. For reference, I'm 6'2", About 155lbs. Should I go for a small? Upsize to a medium? The biggest problem I've had in the past is the arm holes being too loose.

Any help would be appreciated!
Thanks.
