I find them to be true to size, as are all apparel items FJ.
The only area where they are lacking is color selection. The trousers still only come in a limited (solids only) pallette, which is WAY too conservative. Shorts have a much broader appeal since there are more choices.
Been recommending the addition of solids with a chalk stripe in black, navy, and grey for a couple years now. Alas, a lonely voice in the fashion wilderness...
