The Active D+ Classic Support bra for D-H cups offers extreme support and fuller coverage, with a flattering rounded shape. FACT: 44% of women who exercise regularly do not wear sports bras. Inadequate breast support, coupled with excessive breast movement, is the most likely cause of sore and tender breasts after exercise. Also, exercising without a good sports bra can make you uncomfortable, distract you and affect your confidence. FACT: Wearing a Shock Absorber sports bra is proven to reduce breast movement by up to 78%. This has proven to be as much as twice as effective at minimising breast movement as a 'normal' bra.
