This new collection is awesome! Made with lighter weight material (two layers of thin cotton) to still protect but to make much cooler than the typical mask. We now no longer use elastic as the world is always out of stock, so we make our own "elastic loops" with T-Shirt fabric which is so comfy on the ears!!! Easy to breathe while on and won't cause you to sweat. We have many, many fabrics available but requests cannot be made due to the extreme demand.These are not N95 approved but will certainly help! They will be either shipped or ready for pick up in 5-7 business days from order date. Please wait to pick up until you have received an email stating that they are ready.
