I am so glad I have discovered this bra. I play rugby and do a lot of running and gym classes so this bra is perfect for me! I don't feel squashed in as I used to in some sports bras and yet my boobs don't move at all when I run which as a larger chested lady I am so happy about! The bra did feel tight around the back when I first put it on but after about 10 mins I had forgotten about it. It is so comfortable - I won't wear any other sports bra. I would really recommend this bra to anyone who does a running based sport.
