Support level
Built specifically for fuller busts, the D+ Max Support Bra delivers maximum support, exceptional bounce control and lasting comfort.
Bounce reduction: Up to 80.1%
Maximum support when your workout demands it most. The D+ Max Support Bra in Navy has been specially designed for fuller busts, combining extreme bounce control with a comfortable, secure fit that's ideal for running and high-impact training.
Engineered to reduce breast movement by up to 80.1%, the D+ Max uses an advanced supportive construction including encapsulating seams, taped inner seams, a laminated centre front and a strong cetnre front to provide additional support. Fuller coverage creates a secure feel while maintaining a flattering, rounded shape.
Comfort is built into every detail. Shaped, padded and adjustable straps help distribute support comfortably across the shoulders, while the soft, non-wired underband provides breathability and helps minimise chafing. The padded, non-rub hook-and-eye fastening makes the bra comfortable whilst you train.
Breathable, moisture-wicking performance fabric helps move sweat away from the skin and encourages quick drying, keeping you feeling comfortable throughout even the toughest sessions.
Available in D–H cups with non-padded cups. This style fits true to size, so we recommend choosing your usual bra size.

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.
