Best Headgear System I have ever used HANDS DOWN! Comfortable, can sleep in any position, great seal. It does have a pressure relief system that allows air to exit mask from the front of the pillows so if a minor air stream bugs you...then you may want to opt in a different direction but I would say try it 1st. Personally...the little bit of air flow doesn't phase me in the slightest and I have been using this mask for over 4 years now and have never considered another model
