Futures Alpha QD2 3.75 Fins (Small)
The QD2 4.0 Alpha is a performance fin made in the USA, made with an exclusive composite that is carbon and air infused and lighter than Honeycomb. They are a great all around choice, because they provide enough spring to make it around sections while still maintaining some predictability and hold.
Medium (145lbs - 195lbs) (65kg - 88kg)
Alpha is the first of its kind; created using one-of-a-kind materials and new technologies developed by Futures.
Compound 6 is a material blend that is lighter than Honeycomb and the next step in innovation for Futures. Infused with the resiliency of carbon fiber and the lightness of air, C6 is the most advanced injection fin material ever created.
Carbon Fiber has a higher strength to weight ratio than fiberglass. By replacing fiberglass with carbon fiber, the Alpha line is more lightweight & resilient than your standard fiberglass or plastic injection fins. Futures, along with 3M, were able to develop a one-of-a-kind composite material that creates air pockets in the fin to reduce weight without sacrificing structural integrity.
Futures tested various surface geometries behind a jet-ski before a 3D flow texture was developed that controls the separation pattern and influences the boundary layer to reduce the hydrodynamic turbulent wake drag. The result is a more predictable and efficient flow with a significant reduction in the audible whistle heard while surfing called “fin hum.”
The Flat Foil is a very reliable option for all conditions. You will find that they work especially well when making late drops or stalling for the barrel are your primary concern because of their controlled and stable feel.
Carbon Composite - Lightweight & resilient
Water Flow Texture - Decreased Drag & Fin Hum
Air Infused Fiberglass - Lighweight & structurally strong
Calculated Thickness - Flex in all the right places
