Zentek Cooling Mask is here by popular demand..We looked at CDC recommendations ,and our customers requests.. as we always do and came up with this. Masks get hot so we added the cooling material to the inside lining..and they fog up glasses..We added a wire( pipe cleaner) to the top so you can form to your face.We are using the same material that we use for your vests..so they are 3 layers.. the inside being a very lightweight tricot..and bright and dark colors..Boy do we need pretty now! They are edged with a soft lycra that ties around the ears.. CDC recommended that so you can get a custom fit..and you only touch these loops to remove or put on..After fitting..you can cut off the extra..it wont fray.. I just added a flash black mask. It looks black in the daytime but flashes blue or red when light hits it at night. A good nighttime safety mask.
