Although this item fits perfectly and is comfortable it is definitely no use for higher impact activities which was why I purchased it.

This is a very comfy sports bra without wires. Perfect for Long walks/hiking. You can wear this bra all day. I use at the gym for weight training days. I have also jogged on the treadmill for 30 mins in it but I prefer the wired Panche sports bra with wires as it gives more support. It may come up just slightly larger than your normal size but not to big.
