O'Neill Hyperfreak 4/3+ Chest Zip wetsuit is a high-performance wetsuit designed for riders who demand maximum flexibility, comfort, and warmth on the water. Built with O’Neill’s most advanced materials, it is ideal for kitesurfing, surfing, and other watersports. The wetsuit is constructed with TechnoButter 3 neoprene , one of the lightest and most flexible neoprene materials available. It is up to 20% lighter and absorbs 30% less water than traditional neoprene, resulting in faster drying and a noticeably lighter feel in the water. The shoulders, back, and arms feature TB3X neoprene , providing extreme stretch and unrestricted movement—perfect for long sessions where comfort is key. The combination of these materials ensures a snug fit without limiting mobility. With 4/3+ mm thickness (including an extra 0.5 mm for added warmth), this wetsuit is ideal for colder spring and autumn conditions. Its advanced construction minimizes water entry and maximizes warmth, allowing you to stay out longer. The Hyperfreak series is among O’Neill’s premium wetsuits and has won the SIMA “Wetsuit of the Year” award, confirming its top-tier performance and quality.
