Product details
The Marlin is a straightforward open-heel fin that emphasizes durability and an uncomplicated blade response. Bonassi uses a medium blade stiffness rather than an extreme power or split-fin design, making the fin predictable for common recreational kick styles.
The blade is approximately 32 cm long by 20 cm wide on the product and is paired with a flexible elastomer foot pocket. An adjustable heel strap lets the fin be worn with suitable dive boots and makes size changes simple in rental or shared-equipment environments. The combination of polypropylene and elastomer materials is intended to stand up to frequent use.
