While spending the day in the water or on the beach, rash guards protect your skin from chafing and sunburn. Surf shirts are light enough to be worn in warm water and offer protection from the effect of the sun’s rays – even if you’re spending most of your time on the beach or on the boat. Wear rash guards under surf and paddle shirts or wetsuits to protect your skin from uncomfortable chafing and skin irritation where water may collect. Paddle shirts are made of quick-drying fabric and offer the same type of protection for boaters, whose torsos and arms come in constant contact with fresh or salt water. Brands like Body Glove, Billabong, DaKine and O’Neill offer a variety of short- and long-sleeve rash guards to keep you happier in any aquatic environment.
