If you go over to
www.scifihero.net you'll be able to find all sorts of info on the flightsuits as well as reference images from not only screencaps but a screen used flight suit that was on display at ComicCon a couple of years back, as well as one on set. You should also be able to find a link to a Photobucket album that's full of BSG reference images, some of them in hi-res.
