The Tip Jar is for donations for masks for others in need, like the Navajo Nation.
Like all Alpine Luddites gear, these are no nonsense PPE. These masks are made from 2 layers of surgical wrap fabric, which is microporous to .3 microns.
NOT N95 Medical Grade material, and they are NOT FDA regulated. They are a step towards personal protection, but cannot ensure total protection from airborne particles. they now have an bendable steel nose bar. they have nylon tape straps that have cordlocks or can tie around your head. they can be sterilized in an autoclave and repeatedly reused.
They do offer significantly more filtration than a cotton mask.
They ship within 2-3 days .
flat shipping rate.
No returns on masks.
