Spectrum – Boreal Ferrules

The Spectrum Boreal Ferrule is built around layered green and blue tones that transition from light to deep, reflecting the cool gradients seen in northern skies. The color progression evokes boreal light patterns, where subtle shifts in hue create movement and depth without sharp contrast or visual noise. A restrained metallic accent separates the color stack from the base, providing a clean visual break and a precise shaft-to-hosel transition. The cooler palette remains controlled and balanced, giving the ferrule a composed, atmospheric presence that integrates naturally into modern club builds. Precision-made for consistent fit and durability, the Spectrum line prioritizes balance, proportion, and clean execution. Boreal is designed for builders who want expressive color grounded in structure, with a visual identity that feels intentional rather than decorative.
