Product Information


One notable feature of the Plana Avanti X3 fins is their ease of use. The inclusion of the classic ABS system strap enables quick and convenient adjustments with just one hand. Durability is another key characteristic of the Plana Avanti X3 diving fins. They are built to withstand the rigors of underwater activities and are crafted using high-quality materials.

The fins also feature a 3-channel design, which allows the blade to arch during movement. This arching motion enhances the efficiency of each fin stroke, allowing for greater thrust with minimal effort. Additionally, stabilizers prevent water from flowing over the sides. This design element maximizes thrust, allowing divers to move efficiently through the water.

For care and maintenance, carefully read the instructions that come in the packaging to properly maintain the product.
