The Sentry Pro Sigma glasses are designed to offer clear vision in any weather condition. Its SIGMA lenses improve contrast, allowing you to™ recognize every detail in the snow even with changes in light, such as when clouds appear or the sun dazzles.
They have a practical lens change system that facilitates adaptation to conditions. It includes a lens for sunny days with a VLT of 12% (category 3) and an additional lens for lighter fog or snow, with a VLT of 52% (category 1). In addition, they offer complete protection against UVA and UVB rays and have an anti-fog treatment to maintain clear vision at all times.
With an approximate weight of 125 grams, they are very light and comfortable for long days. The triple-layer foam ensures a perfect and comfortable fit to the face, avoiding pressure or slippage.
