Sportswear giant Adidas has introduced a new range of sports bras known as the ‘Techfit Control Bra’ for women suffering from running-related breast pain.

Launched in collaboration with the ‘reactivewear’ engineering company Rheon Labs, the sports bra is made from Rheon’s patented reactive super polymer that adapts to support the breast during high-intensity movements. 

The bra uses strips of strain-rate-sensitive polymer strategically placed across the breast tissue. Like running on wet sand, it only hardens under intense movement, then returns to being soft and pliable. This provides all-around support during activity without being restrictive or overly compressive”.  

The shape, size and placement of each piece is ergonomically designed using computer modeling to offer the optimal support for key muscle groups during exercise.

Overall, the sports bra claims to improve support, reduce wasted energy, and maximise running performance by 7 per cent.

Adidas has also incorporated Rheon into its athletics kits for team GB, France, and Ethiopia at the Paris 2024 Olympics. 

The Techfit Control x Rheon Sports Bra is available online at adidas.com, priced at £65 and available in sizes 32A,B to 48E,G.
