Whether that fourth band matters to you depends on what you are trying to do — but it is a genuine specification difference rather than a marketing one, and it is the reason to pick this mask over the softer silicone alternatives.\u003c\/p\u003e\n\u003cp\u003eThe trade-off is fit. A rigid ABS and polycarbonate shell holds its shape and cleans easily, but it does not contour to the face the way silicone does.
