The Morgan Female Pro guard protects the full chest, including the breasts, ribs, sternum, with the flexible and strong (virtually unbreakable) polyethene guard. The Morgan Pro guard is held firmly in place by adjustable elastic straps and fastened with a standard hook and eye bra fastener. This means any female athlete can wear the breast guard under or over a regular bra or sports uniform. We recommend a light tee-shirt instead of a sports bra is worn under the Pro Guard. A sports bra is not necessary as the Pro Guard already provides full support and is lightweight offering comfortable use.
