To demonstrate Berlei's unrivalled expertise in breast support in a market crowded by ‘althleisure’ brands, we drew on a little known truth about breast movement. When women exercise, their boobs move independently to their body - and often each other.

If you’re playing sport without the right bra to support you, your boobs are literally playing their own game.

Using silicone moulded "boob balls" that bounced like real sports balls, but impacted like breast tissue, we brought this truth to light in a hypnotic, arresting and memorable way, resulting in a huge increase in Sports bra sales for Berlei.
