A Rash Guard (sometimes called aRash Vest,RashieorSwim Shirt) is a type of athletic shirt worn for extra function and protection when surfing, snorkeling, jet skiing, or doing other watersports where you want more protection than aswimsuit, but don't really need a fullwetsuit.  Most rash guards have long sleeves and while some women's tops show midriff, most are regular shirt length.  Of note, they are sometimes worn under a wetsuit ordiving suitfor added comfort.
