Support level
The Active Classic Support Bra in White combines everyday comfort with reliable medium-impact support, making it an ideal choice for everything from gym sessions and fitness classes to active daily wear. Designed for A-D cups, it delivers a flattering, rounded shape while helping you stay supported and comfortable throughout your workout.
A dual-layer support system combines encapsulation and compression. The inner Simplex layer supports each breast individually, while the outer layer works to provide additional support and stability, helping to reduce breast movement by up to 65.4%.
Designed with all-day comfort in mind, the Active Classic features shaped, padded straps and a soft, wide underband that sits comfortably against the skin while helping to minimise rubbing and chafing. Breathable mesh side panels provide additional ventilation and support, while the padded hook-and-eye fastening offers a comfortable fit, even during floor-based workouts.
Made from moisture-wicking, high-performance fabrics, the Active Classic helps draw sweat away from the skin and promotes quick drying, keeping you feeling fresh, dry and comfortable during training.

The band around the chest should be level front and back. It needs to be comfortable but firm — a good gauge is being able to fit two fingers between the underband and your skin. Any more space and the band is too big, and could cause friction.
The underband is firm and level the whole way round.
Only a one to two inch give — neither too loose nor too tight.
If the underband rides up at the back, the band is too big.
The cup should contain the whole of the breast, with no creases and no cleavage on show.
Each breast is fully contained.
If the breasts are squashed or cleavage is on show, the cup size is probably too small.
If the fabric is gaping or wrinkling, the cup size is too big.
Sports bras come in different styles, usually a traditional U back or racer back. The straps should be adjusted to fit securely on the shoulders with only one to two inch give.
Slide two fingers between the strap and the skin — there should be only a one to two inch give.
If the straps dig into the shoulders, loosen them until the fit is comfortable.
If the straps fall off your shoulders, tighten them so they sit securely.
Then do the bounce test. Jump up and down on the spot — you should feel supported and secure, with the band staying level.
