Dérives FCS II Reactor Neo Glass Tri Fins - M

When speed and agility meet: Reactor Neo Glass fins take your surfing to a whole new level. Designed for sessions where every turn counts, they free up your board, making it ultra-responsive in hollow sections and beach breaks. In size M (≈ 65-80 kg), they are particularly suitable for surfers who like to stay close to the pocket, take advantage of the wave wall, while retaining the ability to release the tail for snaps or aerial manoeuvres. The Neo Glass material — a blend of fibreglass and bio-resin — provides a smoother, more responsive feel, while being more environmentally friendly.

Main features:

Neo Glass (Eco Blend) construction: 50% fibreglass + bio-resin; a good compromise between stiffness and flex, with a reduced environmental impact. 

Medium template: recommended for surfers between 65 and 80 kg, or for those who want a lively but controlled setup. 

Reactor template with moderate rake/pronounced verticality: allows for tight turns and quick, precise changes of direction. 

Flat inside foil on side fins: aids stability, precision and hold in carves and snaps. 

FCS II system compatible: key-less design, quick screw-free assembly, strong under load.

Ideal for:

Performance boards (shortboards) with moderate or low rocker.

Hollow, fast or punchy waves, where immediate response is required.

Surfers looking for a combination of liveliness, precision and flow, capable of handling both power and tight turns.
