•The Aqua Lung rash guard fabric is 80% polyester and 20% elastane. Polyester helps keep colors fresh and bright whilst staying undamaged by chlorine. A nylon-elastane blend is breathable, stretchable, and form-fitting when wet. Rash guards made from this fabric are also quick-drying
•All the Aqua Lung rash guards provide UV protection of SPF50 , enough to protect from a sunburn but still comfortable to be worn on bare skin
•A loop is sewn on the front to fasten the strap on men’s surf shorts or swimsuits—this will prevent a roll-up and keep the shirt in shape while you wear it
•A slightly raised neckline gives sun protection during surface activities or stops the buoyancy compensator from rubbing against your skin during warm water dives and helps keep you warm when used as an under-garment
