A lot of you suggested the Moving Comfort brand, which I had been looking into anyway... and I ended up trying out the Rebound Racer:
Muscles, not included.
It had all the things I was looking for... support, racerback, adjustable straps... I ended up ordering it from Zappos.com (because I LOVE zappos.com, #1 no sales tax for TN residents and #2 free shipping and with their distribution center in KY, I get my stuff the VERY NEXT DAY and #3 Awesome customer service).
Anyway, back to the sports bra. So, I received it last week and inspected it...
Ummm... upon first inspection. Not convinced. It looks kinda puny, eh?
I think I expected it to be made out of thick ass spandex and to have titanium rods in it or something. Ya know... like a NASA sports bra.
I put it on (no pictures, YOU'RE WELCOME) and was immediately like... okay... this feels too good to be supportive. It was tight, but light, and besides having to adjust the straps to the maximum tightness, it fit perfectly!
I kinda jumped around a little in it... wondering if it was going to be good enough on it's own to wear it out for a run. I was still skeptical, there was that part of my brain teasing me "put another bra on underneath it... you know you want to!!!..." but, I decided to give it a real chance.
So, I went outside and ran. And you guys, it was awesome!! Who knew that some flimsy, lightweight, comfortable sports bra can be supportive? I'm a total convert and am now going to order a whole bunch more (and ask for some for Christmas). Wayyyy more supportive than my double bra system (even with my old favorite bra).
The ONLY issue I see is that with the lightweight fabric... there's definitely going to be some umm... Nip moments. But, that's not enough of an issue with me to stop wearing this bra. Can't wait to wear it Sunday!
Moving Comfort Rebound Racer Sports Bra perfect for girls with medium sized boobs who are active and shit and are tired of wearing crappy, cheap, old, mangy sports bras.
