The ResMed Swift FX Bella is built for side sleepers and nose breathers who want their headgear out of the way. Instead of a strap that circles your whole head, the Bella Loops hook behind your ears, so you get a lighter, more minimal feel and an open view for reading or watching TV before you fall asleep.Every complete system ships with both headgear styles: the Bella Loops attached to the frame, plus a standard Swift FX headgear with soft wraps if you'd rather wear a strap over your head. You also get three nasal pillow sizes, small, medium, and large, so you can find your fit without ordering pillows separately.This is the gray Swift FX Bella, sized small through large. If you're after the pink for Her version with extra-small through medium pillows, take a look at our Swift FX Bella for Her. And if you'd rather start with ResMed's newest nasal pillow design, our AirFit P10 is the current-generation successor to the Swift FX line.A valid CPAP prescription is required to purchase this mask.
