I'm a 34DD and this bra give me the support I need when I'm at the gym, hiking, or any outdoor activity.  It has held up well to multiple washings, but I never put them in the dryer.  It has adjustable padded straps which are great.  I do have some chaffing when I run so I wear their underwire bra for that instead.  Its good for moderate activities like most gym equipment since I like the freedom of not wearing an underwire everytime I go.  I love this brand and no other company has come close to the fit and feel I get from these bras.  I have to say though I do wear another light sports bra over top of this one because frankly I'm not a fan of the nip show!
