Bought for sleeping in poor condition (on the back of a seat rest in a dimly lit room). He does his job perfectly, not too tight (setting) does not pass light, very comfortable. The gel pouch adds a plus. Personally it is in permanently. Not to cold but that the mask plate even better. Ear plugs isolate noise depending on whether more or less driven into the ear canal. Convenient if you have to wake up. Very slight pouch in terms of quality but filled his office. Only downside, the clips that come behind the head seem fine, seeing the strength in time.
