Casual day playing games and watching soccer with friends yesterday. It was almost 90°, but our friends' house is air-conditioned to a temperature lower than I'm used to, so I ended up in my jacket pretty much all day. I tried Diane's rubber band trick (pic #1) and liked the effect, but it ended up being too fussy for me (and unnecessary with the jacket).

I'm interested in your take on this, because it's a pretty gear-ish look, between the cargos and the athletic jacket, but I think the herringbone pattern (couldn't get the Find to link to the right one) may bring it up a bit from straight "workout attire."
