The toughest of all glass fiber composites. Extremely high strength laminate, with excellent dimensional stability – meaning very little flex, minimal twist and holds shape through all departure changes, Manufactured using multiple layers of lightweight, high tensile glass using epoxy resin as the bonding agent, pressed at high temperature under extreme pressure giving a high glass to resin ratio, making for a super strong composite. Glide uses G10 material for serious wave fins. All tow fins, big wave paddle fins and thrusters for all step up boards.
