Your pre-teen/teen will be super warm and comfortable when they wear this 5mm Junior's THERMOPRENE Wetsuit from Henderson. This fullsuit provides fantastic performance while at a budget-friendly price. Made with Henderson's Thermoprene neoprene, this wetsuit offers 180% super stretch, so there's tons of flexibility and comfort. The neoprene of this wetsuit is also laminated with pill and abrasion resistant fabric. Another important feature to mention is the sealed seams (glued and blindstitched) which prevents cold water from coming into the wetsuit. The edges at the cuffs are trimmed with Lycra for comfort and for chafe resistance. There's a durable back zipper with a spine pad to protect the back and a zipper seal to prevent leakage. Freedom Flex knee pads give needed durability without extra bulk around the knees. The neck is adjustable to provide a customized fit.
