• The Aqua Lung Rashguard fabric is 80% polyester and 20% elastane. Polyester helps keep colors fresh and bright while staying undamaged by chlorine. A nylon/elastane blend is breathable, stretchable, and form-fitting when wet. Rashguards made from this fabric are also quick-drying.
• All Aqua Lung Rashguards provide UV protection of SPF50 , enough to protect from a sunburn but still comfortable to be worn on bare skin.
• On athletic-fit models, the back is longer than the front in order to provide extra sun protection.
• 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 undergarment.

In warm waters, our SPF 50 rashguards protect the skin from UV rays when you're close to the surface and guard against stings, scratches, and scrapes. In cooler waters, a rashguard acts as an insulating layer under a wetsuit.
