When you're engaged in a watersports activity, you don't want wet, irritated skin to distract you. Helly Hansen's Versa Rashguard top ($70, www.hellyhansen.com) employs its LIFA Versa technology on the interior, which moves moisture away from the skin to keep you dry and warm. Polyester in the exterior is elasticized for easy movement. A high neck reduces rash, while exterior seams help avoid chafing to the skin.
