Mares Avanti Quattro + Open Heel Fin - Yellow, X-Large

The Avanti Quattro+ sub fins feature a blade length ranging from 37 to 39 cm, depending on size. The open shoe design and four-rib structure allow the fins to arch during use, channelling water in the opposite direction of motion and minimising loss on the side edges. This transformation of muscle strength into propulsive push is enabled by the material composition, which allows the fins to easily absorb and transmit energy in an optimized manner.

The channel thrust system creates a geometry of channels that can move a significant volume of water, generating a higher boost with the same effort. This performance-oriented design, coupled with the striking perforations in the shoe that prevent the "parachute effect," makes the Avanti Four+ fins well-suited for demanding divers.

The wide central blade of the fin ensures a strong channelling effect according to the channel principle, while the joints at the junction point with the shovel absorb kinetic energy. Available in sizes ranging from S to XL, the fins come in six colour options: Yellow, Blue, Black, White, Lime, and Flamingo.

The key features of the Avanti Quattro+ sub fins include:

1. 4 channels for greater thrusting power
2. Highly flexible material that optimizes blade efficiency
3. Channel Thrust technology
4. Thermoplastic rubber foot pocket and "Tecralene" technopolymer blade
5. Stabilizing trim tabs
6. Bungee strap

These innovative features make the Avanti Quattro+ a performance-driven fin dedicated to the needs of discerning divers, offering enhanced propulsion, energy absorption, and overall efficiency in the water.
