How to find the perfect sports bra?

We have created a simple system to help you select your perfect sports bra. Styles in our Cardio category are perfect for high intensity workouts (think HIIT, running, netball etc.) These bras are designed to minimise bounce as you move around the gym, track or court! If you like to stretch out during a yoga or pilates class, our Studio category styles will be perfect for you. Offering the perfect support for low intensity activities, there will be no bulky clips or textures to distract you when lying in Shavasana.

Why wear sports bra when working out?

When you work out (whether it is during yoga or a HIIT class), extra pressure is placed on breast ligaments. Unfortunately for us ladies, straining these breast ligaments can lead to the dreaded 'S' word…sagging. That is why it is important to support breast ligaments by wearing a sports bra when exercising. Read more about how to prevent your breasts from sagging!
