This bra worked well for me for a long trip in somewhat rugged conditions.  It looks fine under thinner shirts and white shirts, washes well in a sink, and dries quickly.  It isn't exactly gorgeous, but I was happy with it and was able to get by with just two of these for a 25 plus day trip.  I would add that I'm fairly small on top, so my support needs aren't as great as some women's.)
