Patagonia shirts?

[matt2]

I'm thinking of ordering one of these to add to my casual shirt arsenal:

Does anyone have any insight into their sizing? I realize these are probably too casual for most here but they're a popular brand in my line of work (wildlife biology) and would likely fit in well with my office, assuming the fit is good.

I'm a big fan of Patagonia. I'd say that shirt is probably pretty true to size. Their clothes definitely are not slim fitting, unless it says otherwise in the description.
