The RK3 Fin was designed in collaboration with the US military and is renowned for its exceptional performance and reliability. It is a fin made of durable thermoplastic rubber, with an oversized foot pocket that accommodates drysuit boots and an elastic strap for easy wearing and removal.

• Material: Durable thermoplastic rubber
• Foot pocket: Oversized for drysuit boots
• Strap: Elastic for easy use

The RK3 model does not have a shoe size range, as this can be misleading. The environment in which the RK3 is used will determine the fin size required. It is important to try the fins with your own footwear to ensure the proper fit for the type of diving you prefer.
