The best part is you can wear this while you work and play. Since the Outdoor Research team is full of active and outdoor-loving employees, you know that being able to wear a mask during physical activity was top of the list when it comes to design. Because the mask sits above your face, and not directly on top of it, you’ll find that it’s much easier and more comfortable to breathe in than other masks on the market. But one of the most unique functional designs is the built-in HeiQ V-Block. According to Sara Nazim, Outdoor Research product manager for accessories, “This is an innovative Swiss antimicrobial technology which makes treated textiles resistant against spoilage from microbes.” In other words, this technology makes your mask extra-resistant to viruses and protects it from becoming bacteria-infested. HeiQ V-Block is also hypoallergenic and composed of 100% cosmetic ingredients, so you don’t have to worry about any harsh chemicals coming in contact with your skin.
