disappointed
Quality materials and workmanship but design is poor. Uses heavy twill type fabric so the seam over the bridge of my nose is 4 layers thick and that results in constant pressure, no matter how I adjust the strap tension. The metal nose wire is weak; it won't hold its shape.  Doesn't conform to cheekbone area so constantly fogs my glasses. That also means air is bypassing there on inhalation. It may work for people with a snub nose but not for me.
