Whatever your activity, Tryst has the support you need. Sports bras are available from an A cup to a J and offer varying levels of impact control. Sports bras come wired or not and both will give you comfort and flexibility while you work out. It is important to wear a sports bra while exercising because not only will it minimize bounce but sports bras are designed to not inhibit range of movement and to hold up to sweat and impact better than an ordinary bra.
