Tsek Corona VK mask.
These masks are made from scuba material (Neoprene) for longevity and premium comfort during winter. Due to the properties of Neoprene, these masks are not required to be 3 layers as 2 two layers do suffice for safety and durability.
These masks have one toggle back and one tie back, so it's adjustable for any size head and to give you room to breathe comfortably. The toggle back also allows you to just hang the mask around your neck when the mask is not needed.
Washing instructions are included with each mask.
