Breath easy with this reusable face mask from Dr Jon. These washable cloth masks come in a variety of stylish colours and are eco-friendly. The five layers of cloth offer maximum protection and the adjustable ear loops allow you to customize the fit. The exhalation valve is nestled behind three of the five cloth layers. You'll inhale through five layers and exhale through three, making breathing easier and prevents the fogging of glasses. Masks are fitted with a filter sleeve to allow for the optional addition of a Dr Jon filter (sold separately). One size fits most.
