I have always used shock absorber bras for the gym. I have had about 7 or 8 all together. This one seems to let them brand down. To start with it is a nightmare to do up. I have to do up the top clips and then put it on over my head to then struggle to reach the lower clips to do it up. I have to put it on at home as it's too embarrassing to do that at the gym! The fit is a little tight and because of this the elastic has started to go. Little bits of elastic now show through the bra as they are slowly snapping. The support is good but not worth it in my opinion once you've struggled to get the thing on. You've then got to get it off! On the bright side you do burn calories trying to get your arms to unclip it.
I'd recommend shock absorber but a different style.
