The O'Neill Youth Epic 3/2 back zip is our most popular children's full length wetsuit and for very good reason. We love the stretchy neoprene, seam free paddle zones (meaning there are no seams under the arms), double seal neck closure, glued and blind stitched seams and the covert blackout back zip (all three meaning less water will get in).  In the 3/2 thickness it will keep you warm during the summer months and its stretchy UltraFlex Neoprene gives you unrestricted movement in your shoulders and arms. Enjoy the beach this summer!  3/2mm100% UltraFlex NeopreneKrypto knee padzStrategic seamless paddle zonesLumbar Seamless DesignUpdated Velcro closureFluidFlex™ FirewallGlued & Blindstitch Seam constructionGlued in covert zipper contruction with Back-out zipperDouble super seal neckExternal key pocket with loop
