That's the definition of comfort! You can open and close them with two fingers. . .very easy! You can even fit 2 pairs of reading glasses in it if you want. They fit ALL glasses and sunglasses EXCEPT the largest. . .which are popular now. I have some "Jackie O." style sunglasses and some "J-Lo" style sunglasses (both Steve Madden) that fit with the soft leather opening pushed back slightly. But I have some ski bunny colors (from Armani Exchange) that don't work. In any case, the quality and workmanship is excellent. I have a beautiful red and a rich brown.
