The material for this mask is soft and very comfortable. Freezing the gel pack and trying to use it in the mask left me feeling like my eyeballs were headed toward becoming ice cubes, so I refrigerated it instead.
My problem with this mask is in its design: it doesn’t adequately cover the eyes, and without shape around the nose, lets even more light in. I’d rate the overall comfort at a 7/10.
I’ve gone back to using the one I got on an airplane years ago.
