The Oakley Holbrook XL combines its heritage-inspired silhouette with advanced optical engineering for professional-grade performance. Featuring the original Holbrook design scaled proportionally to accommodate medium-to-extra-large facial dimensions, this model integrates O Matter™ frame construction for lightweight durability and all-day wearing comfort. nnThree-Point Fit engineering ensures precise lens alignment and stability during prolonged use. Prizm™ lens technology optimises environmental perception by selectively enhancing colour wavelengths and contrast ratios for improved detail recognition in variable lighting conditions. Optional HDPolarised lenses utilise single-layer infusion moulding to eliminate glare while maintaining true depth perception. nnPlutonite® lens material provides ANSI-compliant impact resistance with full-spectrum UV filtration (100% UVA/UVB up to 400nm) and reduced blue-light transmission. The design retains signature elements including metal rivet detailing and keyhole bridge architecture, offering a professional aesthetic suited to corporate branding applications.
