Scottish-based brand Screen & Shield doesn't use materials or manufacturers needed by the medical community to create its line of Screen & Shield Washable #SASMask (£10, originally £12), which are made of three layers: cotton (which goes against your face), a centra polypropylene layer (that acts as a shield for respiratory droplets), and an outer polyester layer. A flexible nose wire and contoured shape make these masks great for glasses wearers, as they won't fog up your lenses. Available in a wide variety of patterns and prints (and kids sizes!).
