O’Neill Youth HyperFreak 5/4+ Chest Zip w/Hood is a high-performance junior wetsuit designed for young surfers and watersports enthusiasts who need maximum warmth, flexibility, and comfort in cold conditions. Featuring an integrated hood, 5/4+mm neoprene, and O’Neill’s advanced TechnoButter 3 and TechnoButter 3X materials, it combines lightweight performance, unrestricted movement, and effective thermal insulation.
The HyperFreak F.U.Z.E. (Chest Zip) construction uses super lightweight TechnoButter 3 and TB3X neoprene, providing a soft and flexible feel while maintaining excellent warmth and durability. The minimal seam design, lightweight construction, and attention to detail make this wetsuit a popular choice among young active watersports riders.
The watertight F.U.Z.E. Chest Zip system reduces water entry and provides a comfortable, secure fit. The integrated 360° Barrier with Drain Holes helps prevent water flushing while allowing excess water to drain away from inside the wetsuit. TB3X Fully Taped Seams combined with Glued and Blindstitched (GBS) seams improve insulation, flexibility, and durability.
The Plus (+) construction adds an extra 0.5mm of neoprene, providing additional warmth compared to standard models without limiting freedom of movement.
