“I have a similar tee I got from Holabird a couple of months ago, with the Saucony name located a little higher on the shoulder. It is the best tee I've ever had. Problem is, the sizing. The tee I have is a medium, and fits nicely snug. The medium size for product offered here is 39-40 My comfortable size is 34-36. I know there is a lot of variability in sizing, but this is ridiculous. How is it that Saucony has such absurd differences in what is supposedly the same size?”
I've experienced this myself, and it seems to come down to style / purpose, as in compression, base layer, fitted, loose. Thel measurements and fit vary while the actual size stays they same. I thought the measurements would reflect that of the body's measurements, not the intended fit, but it seems to be based on the way it should fit. Larger measurements = relaxed/looser fit, and vise versa.
