How many race shirts do you have that sit in a drawer because they are too big or too small? Race shirt sizing is a big pet peeve of mine.
I wish race directors would post a sizing chart for their shirts or at least say whether the shirt is going to be cotton or technical fabric. I need a small (or smaller) in unisex technical shirts but I always get a medium in cotton t-shirts, so I am always torn when it comes time to put my shirt size on the entry form.
Three too large shirts later, I think I will be putting "small" down the next chance I get!
