The name Rashguard reflects the fact that the shirt protects against rashes caused by abrasion or by sunburn from extended exposure to the sun. But the latest trendy Aqualung rashguards can do a lot more that that; they are designed to be worn both in and out of the water while providing sun protection, ward off jellyfish stings or add an extra layer under your Aqualung dive suit.
The aqualung rash guard fabric is 80 % polyester and 20 % elastane. Polyester helps keep colours 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 aqualung rash guards provide UV protection, enough to protect from a sunburn but still comfortable to be worn on bare skin. 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.
