I want one. But I'm unsure of the sizing.

Here in Canada, things are sized by the American system, where a real "Medium" is often labelled as "large", and a real "large" is labelled as "XL (eXtra Large)", etc..

I normally get an XL, which then shrinks to a Medium, which fits perfectly. So if these are at all shrinkable, put me down for a "fat bastard", and it should all work out in the wash!

Thanks
