Description OMS Slipstream Fin The OMS Slipstream Fins are a popular and highly-regarded piece of scuba diving equipment, particularly among experienced and technical divers. They are known for combining the classic, rugged design of a “jet-fin” style with a modern, lightweight material. Key Features Material: They are constructed from Monoprene (an injection-moulded thermoplastic elastomer), which is a modern material designed to deliver rubber-like performance but with a much lighter weight. Buoyancy: The Monoprene material results in a neutrally buoyant fin (or slightly negative in some contexts), which is a key feature. This helps divers, especially those wearing wetsuits, maintain better trim (horizontal position) in the water without their feet sinking too much. Design: They utilise a proven, classic open-heel, vented blade design, similar to the original Scubapro Jet Fin. Vented Blade: The vents or flow channels in the blade are designed to increase propulsion while reducing stress and drag on the diver’s leg during the kick. Spring Straps (Included): The fins come standard with durable stainless steel spring straps (often with a nylon sleeve to prevent pinching). Spring straps are favoured by technical divers for easy donning/doffing and automatic adjustment for boot compression at depth. Performance: They are known for providing excellent thrust and power with a slow, easy kick. Their stiffness and design make them particularly well-suited for specialised fin techniques like the frog kick, back kick, and helicopter turn, which are essential for technical and wreck diving. Weight: They are significantly lighter than traditional rubber fins of a similar style (like the Scubapro Jet Fins), which helps reduce leg cramping and fatigue during long dives and makes them more travel-friendly. Target Audience: Extremely popular with experienced, technical, and cave divers who value precision and durability.
