Cold-weather face protection has traditionally been designed for breathability, but with global pandemics a real threat these days all the breath holes in our cold weather gear make it difficult to comply with many of the new regulations for face coverings. But instead of tossing aside your trusty mask or ComboClava® you can just add an adjustable BIO mask filter and breath easy again. The BIO mask filters come in a pack of 5 and feature a pliable copper nose bridge and creates a barrier that perfectly covers the holes in your go-to face protection so you don't have to settle for something less warm this season.
