Pros: - Comfortable, I barely notice I'm wearing it. - Zero contact with eyes. - The elastic strap has an adjustable length, and is long enough for those with big heads like me. - No smell. - No dye has rubbed off.
Cons: - A little bit of light leakage at the bottom, between my cheekbone and my nose. If I needed to sleep in full daylight that'd be a problem, but in relatively dim conditions (e.g. shades drawn, or on an aircraft) it's good enough.
