Nasal masks fall between Pillow and Full Face masks when it comes to weight. They're fantastic for back sleepers due to the way the hose plugs in. These also go well with facial hair, whether you're going for the majestic Gandalf look, a shorter Thor style, or a handlebar mustache.

Nasal masks won't work as well if you sleep on your stomach, have nasal congestion issues, or if you breathe through your mouth.
