If you prefer a full face coverage with all of the extra features you can think of, the 3-Layer Deluxe Olson mask is for you! If you need something that will give you the most protection with the least amount of contact with your mouth then the 3-Layer 3D Pleated masks are going to be the most comfortable option. (Ex: if you work in an environment where you need to speak with customers all day while wearing a mask). That being said - the comfort level of either style is completely based on personal preference, and both styles have been specifically designed to keep you as safe as possible based on government recommendations for handmade masks.
