Aplat mask with easy on, easy off ear loops. The optional tie can be used to secure your mask when off and hung around the neck. All our masks are made from tightly woven 10oz, preshrunk, 100% organic duck cotton canvas. The double-layered origami construction provides an adjustable fit, comfortable breathability, and are free of plastic, elastic and metal, making them 100% biodegradable.
