The O’Neill Hyperfreak Fire 5/4+ mm is a warm and flexible women’s winter wetsuit designed for cold-water surfing and demanding winter sessions. It is ideal for women who want maximum warmth without compromising comfort, freedom of movement or performance. The wetsuit is made with next-generation TB4 Firewall neoprene and heat-retaining fibres infused with graphene. This advanced construction helps preserve body heat while remaining highly flexible, making it easier to paddle, perform take-offs and move naturally on the board. Fluid Seam Weld seams help reduce water entry, while Fused Super Seal Cuffs create a secure and comfortable seal around the wrists. Together, these features help keep cold water out and allow you to stay warmer for longer during sessions in low temperatures. Warmth and flexibility for cold-water surfing The Hyperfreak Fire 5/4+ mm combines the insulation of a thick winter wetsuit with the flexibility of a high-performance surf wetsuit. Its stretch construction follows the body’s movements and reduces the stiff feeling often associated with heavier neoprene suits. It is well suited for surfing, kitesurfing, wing foiling and other cold-water sports during autumn and winter.
