I love Title 9 in theory, but a warning: they rarely list the manufacturer of their bras or other clothing items, which can be really annoying if you are someone who is pretty familiar with various brands of athletic clothing. You can get the idea that an item is some exclusive Title 9 product, when it's actually something far more common. I know a lot of their bras are by Moving Comfort, but I think only a few of them actually say so in the product description.

A story that might only be funny if you are my husband: I was going through the catalogue this summer, circling stuff I liked, and I pointed out a pair of capris that I really loved. "If those weren't so expensive I would ask for them for my birthday!" His response: "Uh, Beth?" as he pointed at my legs. They were the same Prana capris that I'd purchased for myself at Back Country Outlet a month or so before. And I was wearing them at the time.

But I second or third the Moving Comfort suggestion because those are my favorite wicking bras -- they aren't supportive enough for me for anything high impact, but I use them for travel, like when we go to the Yucatan and it's so humid that you are drenched in sweat as soon as you step out of the shower. If you are small breasted you might also like the Patagonia capilene line. They don't fit me very well but the fabric seems pretty good.
