Unlike any other CPAP mask, the F&P Evora is simple, intuitive and feels comfortable the very first time you wear it. Evora's unique CapFit headgear is worn just like a cap so it's naturally easy to put on and take off. The compact floating nasal cushion gently wraps around the nostrils, without pressing inside them, for a soft, secure seal. This F&P Evora FitPack includes three cushion sizes -- Small, Medium and Large -- so you'll be sure to get your best fit right out of the box.
