KnockerLocker Sports Bras

KnockerLocker brings you the latest in premium sports bra shopping. No matter your breast size or preferred sport, we have the right sports bra for you. We also have know-how to guide you towards it.

Check out our innovative Power Rating. This useful tool combines your breast size with the impact level of your chosen sport. This gives you a ‘Power Rating’ from 1-5.

You can then filter our sports bras to find one that will deliver the enough support for your breasts in your activity.

Breasts come in all different shapes as well as sizes. Some shapes will fit better in particular sports bra brands than others. So have a read of our breast shape descriptions. Identify which you are and have a peek at our sports bra recommendations.

Use our bra size calculator and fitting guidelines to ensure you are wearing the right size in your current bras.

We test all of our sports bras and give lots of guidance about each brand’s sizing and fit. Find out more in a free online fitting.
