A Powerful Partnership.

At Berlei we’re dedicated to engineering sports bras that offer women the best protection when they’re exercising. We are the only bra manufacturer that works with the Australian Institute of Sport (AIS) to deliver a product that actually reduces breast bounce.

Research conducted by the AIS has revealed that during high-impact exercise an unsupported 12B bust can bounce up to 8cm, and a 16DD bust can bounce up to 19cm! This movement can damage soft tissue and stretch delicate Coopers Ligaments, which can ultimately cause breasts to sag.

AIS test results prove that Berlei’s Electrify Underwire sports bra can reduce breast bounce by up to 50%.

We use AIS testing to assist us when we’re designing our superior sports bras, and also to help us educate women about finding the appropriate level of support for their breasts when exercising. AIS helped us develop the Berlei Sports Bra Support Factor (SF) rating system, a unique rating system for sports bras that helps women choose the right bra for their needs.

Berlei’s SF Rating System.

Walk run or jump, Berlei understand that you need serious protection. Our Support Factor (SF) rating system makes it easy to find the protection  you need when exercising.
