COMPARISON: NEO GLASS ECO VS GLASS FLEX
| Criterion | Neo Glass Eco (this product) | Glass Flex |
|---|---|---|
| Material | 50% fiberglass + bio-resin | Technical polymer |
| Flex | Active and progressive | Softer and more uniform |
| Performance | ++++ (drive + hold in turns) | +++ (forgiving and predictable) |
| Eco-responsible | ✅ Arkema / Pragati Bio-resin | ❌ Classic Polymer |
| Who's It For? | Light and agile surfers | Beginner to intermediate |
Verdict: The Neo Glass Eco delivers a more active flex and superior performance compared to Glass Flex, all while being eco-responsible. Glass Flex remains an excellent choice for beginner surfers seeking a forgiving and affordable fin.
DETAILED DESCRIPTION
The Performer template: Find Balance
The Performer is FCS's ultimate allround template. Featuring a well-proportioned profile and Inside Foil Technology (IFT), these surf fins deliver a remarkable balance of speed, flow, and responsiveness. They're ideal for surfers who demand a reliable fin in all conditions, from small beach breaks to the more consistent waves of point breaks. This combination of drive and handling allows for smooth transitions between turns.
Neo Glass Eco Blend Construction
The Neo Glass Eco Blend range showcases FCS's commitment to sustainability. Constructed with 50% long-fiber fiberglass and castor-based bio-resin, these fins reduce fossil fuel use while still offering high performance. The active and progressive flex is recommended for lighter, more agile surfers who seek responsiveness and hold in turns.
Pragati Initiative: Sustainable Surfing
The Eco resin is created by Arkema, a founding member of Pragati, the sustainable castor initiative. This program trains local farmers in ecological practices, improves their income, and ensures better living conditions. By choosing the Performer Neo Glass Eco, you're surfing with a reduced carbon footprint without compromising performance.
Two Colors, Same Performance
Available in Pacific Blue and Mango, the FCS II Performer Neo Glass Eco surf fins offer exactly the same performance, regardless of color. The Mango color currently benefits from a -30% sale, making it an ideal opportunity to discover the Eco Blend range at a reduced price. These fins are compatible with all boards equipped with the FCS II system.
