The Ninja 4/3 Youth Chest Zip Wetsuit from O'Neill is built for young surfers who need reliable warmth, flexibility, and durability in cooler water conditions. Designed as a high-performance all-round winter suit, it balances insulation with freedom of movement for progressive surfing.

Constructed with UltraFlex neoprene and FluidFlex Firewall insulation, this wetsuit provides warmth where it’s needed most while maintaining stretch in key movement zones. The chest zip system helps reduce water entry, keeping sessions more comfortable in colder conditions.
