The Heat-Shield Neo-Front Rash Guard is a hoodless option in our game-changing UV Top Series. Like the Hooded Convertible Neo-Front Rash Guard, the Heat-Shield features a 1.5mm perforated neoprene front panel that provides a perfect amount of rib/abs padding for pain-free warm-water sessions, while the perforations allow free-flow of water to keep you from overheating. The stretch nylon fabric and neoprene panels are certified at 50+ SPF rating for all-day protection. Key Features and Benefits: 1.5mm perforated neoprene front panel prevents abs rash and sore ribs while allowing water-flow to keep you from overheating. 200 GSM Nylon/Spandex arms and back panels for the perfect balance of durability, UV-block, and stretch. Full-size rear zipper-pocket can hold reef boots, sunscreen, and food/water. One-hand adjustable waist cinch and boardshort loop keeps everything in place during heavy wipeouts. Sizing Recommendations: For optimal performance, these rash guards should fit snug but not uncomfortably so. We recommend going with your normal T-Shirt size. Sizing is based on US-Men's shirt sizes. The Heat-Shield works perfectly in concert with our Convertible Watersports Hat or our new Convertible MAX Watersports hat for full upper body sun protection.
