O’Neill Youth Epic 4/3 Chest Zip Full is a warm and flexible junior wetsuit designed for surfing, windsurfing, kitesurfing, and other watersports in cool and transitional conditions. Featuring 4/3mm neoprene, F.U.Z.E. Chest Zip entry, and O'Neill's flexible UltraFlex neoprene, it delivers an excellent balance of warmth, comfort, and unrestricted mobility.
The 4mm neoprene in the torso provides effective thermal insulation, while the 3mm panels in the arms and legs maximize flexibility for natural movement. The F.U.Z.E. Chest Zip entry minimizes water entry and creates a more secure fit than a traditional back zip, helping young riders stay warmer for longer.
The FluidFlex Firewall thermal lining enhances warmth during colder sessions, while the Glued and Blindstitched Seams (GBS) reduce water penetration and improve long-term durability. The Double Super Seal Neck and elastic wrist and ankle cuffs further help prevent flushing and keep the wetsuit comfortable throughout the session.
Reinforced Krypto Knee Padz protect high-wear areas, while the integrated key pocket with a securing loop provides convenient storage for a key.
