Junior wetsuit with long sleeves and long legs. Made of 4.5 mm thick neoprene, and in critical areas—most prone to cooling—5.5 mm. In addition to providing thermal comfort, neoprene also minimises the risk of skin chafing. The O'Neill Hyperfreak Fire series focuses on extreme warmth, high flexibility, increased durability, and comfort—TechnoButter 4 Firewall is one of the most insulating and lightest neoprene suits in history, with a heat-retaining inner thermal layer and quick-drying properties. These advanced materials and the Fluid Seam waterproof construction create legendary insulation from cold water.
It features a front zip. Its placement on the chest not only facilitates putting the wetsuit on but also minimises the amount of water that enters inside. The fitted cut and ultra-light flexible TechnoButter4 materials ensure great body adherence while offering complete freedom of movement. A more durable material is used in the knee area. The seam-free area around the armpits increases comfort and efficiency while swimming.
