I have 2 pairs of the board shorts. The first pair, bought in 2007 fit me a bit snugly, but well. I like the length, not too long or short. The liner shorts are OK. Not the chamois I would choose for regular cycling shorts, but it's OK. The second pair I bought in 2008. They are big, compared to pair #1. It's very weird. Both are x-smalls and both were bought on TE. Companies change things from year to year, so I chalk it up to that.
I wear the shorts mostly for casual things, without the liners, but I have worn them with liners when I ride around town to do errands on my commuter bike.
I have an acquaintance who has the capri length ones. She likes them, but she is of average height; I am short and on me they would be like cropped pants.
