Let's All #MaskUp! Help us slow the spread of COVID-19 and protect those most at-risk by wearing a mask. These special masks are made by Primal Wear. The patented X-frame design lifts the mask's fabric off of your face, providing superior airflow. The NT3D reusable filter can be washed 10 times, without losing any filtration efficiency. The steps are extremely adjustable so you can achieve the perfect fit.
