With classic designs that are kinder to the planet and optimized for performance and efficiency, whether recreation or technical diving, there's a pair of Fourth Element fins however you explore. Part of Fourth Elements OceanPositive range, they've used recycled, natural and recyclable materials in the manufacturing of their fins and each pair comes in zero plastic packaging, eliminating plastic waste and reducing the impact on the environment. A classic vented fin, redesigned to maximize performance. Utilizing natural rubber in a unique density gradient, this fin delivers a comfortable foot pocket combined with optimized stiffness for finning performance. The vented design allows water to flow along the blade reducing drag and fatigue, whilst the stiffening rails and ribs ensure that the blade of the fin is driven through the water to maximize the return on effort. The Tech Fins was developed with technical divers in mind with a slightly negative buoyancy characteristic but is suitable for all levels of diver looking for a high-performance rubber fin. The wider blade gives maneuverability without compromising the power which is there when needed, while the shorter length improves agility and makes stowing the fins for transport more convenient.
