The RollFit XT seal for the Fisher & Paykel Vitera rolls back and forth on the bridge of your nose, which means:

- The freedom to move as the mask adapts to your different sleeping positions, helping to maintain a comfortable seal and minimize leak

- Reduced pressure and soreness on the bridge of your nose. The RollFit XT seal, which covers the nose and mouth, is designed to operate at a range of pressures from low to high.

There are three seal sizes available: Small, Medium, and Large.
