- Would you recommend 3RD ROCK to your friends? 1 - No, not at all2345- Yes, very much
The main thing I absolutely love about 3rd rock bras is that they fit so many sizes. I have a really small back size but a big cup size and I just love that these bras accommodate me (majority of sports bras really don't). This is so comfy and looks great. It's really lightweight too which is a bonus. Thank you!!

Fits perfectly, not too tight. Great support. Great movement. And I love that it's not too low at the front!

Comfortable, and a pretty good fit, although I would recommend getting a large if you are a petite DD. Fully reversible and gorgeous on both sides. Suitable for things like yoga but doesn't provide enough support for active work, if you are larger in the chest (size D upwards at least)
