Rip Curl Youth Dawn Patrol Long Sleeve Jacket is a zipperless wetsuit jacket that is perfect for young groms to wear in the surf and for any water sports. It is 1.5mm thick meaning it can be worn all year round and is great for some extra warmth and for sun protection. Rip Curl's dawn patrol range features their E5 neoprene and E-Stitch high stretch seams. E5 Neoprene will keep the kids core warm in the water without compromising on its flexibility meaning it can match whatever movement gets thrown at it. The seams of the jacket are E-Stitched, which means like the E5 neoprene the stitching is light and flexible which is important if you want to get anything out of the flexible neoprene it's holding together.
