So I was a bit unsure of these sports bras reading other reviews. The comments were generally "nice fabric" or "I love the colours". However, what I wanted to know was 'can I run at pace in these without anything wobbling and being sore at the end of a training day??' I took the leap and bought two and I can confirm, as a world champ level ironman athlete, I have stress tested the living daylights out of them. Long run sessions, short fast, intense sprint sessions, on the bike etc and I have not been disappointed! The 'girls are very happy' The only thing I worry about is the elastic in the bottom twisting after washing - so far so good though?. But that is really my only concern. So whether you're a serious cardio athlete or a gym/ yoga swan, I would give these a go. :) I'm a 34 B - medium fit me perfectly! Happy training!
