I would be able to help, as I have just ordered up the 2010 ones… but in small! So it probably wouldn’t be much help to let you know how they fit!
I think there is a sizing chart on the page for either the 2009 ones or the 2010 ones. Can’t remember, but I am sure that I saw one on there somewhere. If in doubt, try a search for a Mace clothing size chart.
I just don’t understand why with cycling clothing, they can’t tell us what measurements the different sizes accomodate…
EDIT: just re-read and realised that you have found the chart!
I would go by the chart. If you do, I doubt you will run into any problems. And if you do, you can always send them back 🙂
