Description
The Mares AVANTI 4X fins represent the evolution of the iconic Avanti Quattro +, engineered for scuba diving with a focus on propulsion, control, and all-day comfort. Their sleek, modern design is tailored to pair with standard diving gear while delivering reliable performance across open-water and reef sessions.
Dual-material construction optimizes the foot pocket and blade integration for a secure, responsive fit. The 4-channel blade system generates powerful thrust while reducing fatigue during longer dives. Stabilizing side ribs with an over-molded finish blend function with style, and the bungee fin strap with an anatomical heel pad provides easy adjustment and a secure hold. Available in sizes XS to XL to accommodate a wide range of divers and gear setups. A reusable quick-dry mesh bag adds eco-friendly packaging for easy transport and storage.
