The mesh fabric is not clingy which helps with natural ventilation. The material has built-in stretch, is quick-drying and moisture-wicking, and has UPF 50 for outstanding sun protection. There are thumbholes for added sleeve protection, a ¼ Zip neck, and a square hem to wear tucked or untucked. The DPF Performance Mesh ¼ Zip is a versatile technical top that looks great on the boat or at the gym.
