This is the most comfortable, simplest mask I've ever used and I will never use anything else. The headgear is soft and very easy to adjust. The configuration of the headgear ensures it stays on your head, no slipping. The nasal mask is very comfortable with a minimum of leaks, if any. There are only four parts that all click together which make it very to clean. I have tried more masks than I care to remember from full face to nasal pillows to nasal only. My problem is I'm very petite, my feet are small, my hands are small and much to the amusement of my family, my head is small. This is the only mask that fits me well, and I love it.
