The O'Neill Hyperfreak Youth 5/4+mm Chest Zip wetsuit is a futuristic number for 2024, with fully taped seams keeping water out and flexibility high. It's fitted with extra 0.5mm Technobutter 3 neoprene on the body for extra warmth, plus 0.5mm 3X neoprene on arms and shoulders for great flex.

We always get excited for a fresh wetsuit, and this one's Technobutter 3 & 3X Neoprene is plain amazing. Softer than a shirt and more flexible than ever before.

It'll keep you comfy in the water and its pre-stretched Techobutter will never lose shape. The inner suit features draining lines so no aqua fills the suit and you'll have an amazing time with this game-changing wetsuit.

Note: O’Neill Wetsuits products can only be shipped and delivered to customers within the European Union (EU).
