Ultra-Tough Multi-Coat by SOLA is AR Technology - Engineered to Last. An advanced anti-reflection coating, UTMC uses technology that chemically fuses the AR with the hard coat and lens material so they bond inseparably. The patented anti-static formula repels dirt, while the Ultra-Tough hard coat provides excellent scratch protection and durability.

UTMC3 - the third generation of UTMC AR technology adds a super hydrophobic, super oleophobic top coat to repel water, oils and dusts and make the lenses extremely easy to clean and keep clean.
