This is a remix of the Montana mask that I made for my dear coworker Zhaina who complained that the Montana mask did not fit her beautiful Black face. I tinkered and elongated the mask, made it roomier and added a ridge around the filter opening so the filter block can only come out the h some prototyping, we found that folks with longer noses liked these as well as guys with fabulous facial hair. We've been using Bio-smart fabric in small squares as our filte or quilter's cotton print and it seems to work well. It's easier to breathe in than fabric masks in the summer heat Be safe out there!
