From the very start Oakley® has been committed to providing professional and everyday athletes around the world with solutions to support their performance passions and day-to-day activities. Designed with seal, filtration, fit and eyewear integration in mind, Oakley has launched Oakley MSK3, a mask designed to work seamlessly with eyewear and fit snugly on the wearer's face. MSK3 includes two filter options for filtration and breathability. The high-performance, disposable filter has over 95% filtration efficiency of particles down to size of 0.3 microns, while the additional reusable filter is designed for filtration protection against air pollutants and dust particles. Replacement high-performance filters and reusable filters are available for purchase.
