I like the Primos face masks. They are relatively inexpensive, come in a lot of colors, and a variety of configurations. I also use a boonie that has a mesh mask stitched into it. Don't leave home without...
Yup I use the knit pull over face mask in the winter & if its real cold I pop on my white painters face mask under it...I stay warm!
The summer months I use a camo balcova or a mesh leafy face mask.
I will use a camo neck gaiter that I can pull up on my face when it is really cold. Along with a beanie the only thing exposed are around my eyes.
When it is not subzero I will wear a shemagh around my neck and can pull it up to help conceal my face if needed. More often it is to keep blowing dirt or snow out of my nose and mouth.
