This maximum support sports bra top from Shock Absorber is a popular crop top design with internal cupsize support.It features shaped, padded and adjustable straps for extra support and is made from moisture wicking, breathable, high performance fabrics. Getting the right fit is important to a good performance - To ensure your sports bra gives you the best support, here are some tips to achieve the perfect fit. The Underband - The band around the chest should be level front and back. It needs to be comfortable but firm. A good gauge to ensure that the underband fits well 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 Cups - The cup should contain the whole of the breast, with no creases and no cleavage on show. If the breasts are squashed or cleavage is on show, the cup size is probably too small. If the fabric is gaping or wrinkling then this suggests the cup size is too big. The Shoulder Straps - 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.
