SIZING: The silicone portions of all Swift FX Headgear Assemblies are the same size; however the Swift FX For Her Headgear includes additional notches at the back to accomodate smaller head sizes. The Blue Swift FX Back Strap is larger than the Pink Swift FX For Her Back Strap.
COLOR: Blue headgear, with gray Soft Strap Wraps, comes standard with all Swift FX Nasal Pillow Masks. Pink headgear, with pink Soft Strap Wraps, comes standard with all Swift FX For Her Nasal Pillow Masks.
COMPATIBILITY: Swift FX Headgear Assemblies are interchangeable, so either headgear color can be used with any Swift FX or Swift FX For Her Nasal Pillows Mask. Swift FX Headgear can also be used as an alternative to Bella Loops on all Swift FX Bella Series Nasal Pillow Masks.
NOTE: While the fittings are compatible, Swift FX Headgear Assemblies are NOT recommended for use with Swift FX Nano Masks. This is due to subtle differences in the mask design required to position nasal pillows properly against the face.
