The FlexiFit 431 full-face mask incorporates FlexiFit technology with its self-moulding properties, features an under-the-chin design, and comes with a high-quality satin-finish silicone seal for maximum comfort and stability.

The FlexFit 431 full-face mask offers a comfortable alternative to nasal and oral masks, and comes complete in a single box, already assembled and ready for use.

FlexiFit technology (Self-moulding with air cushion):
FlexiFit technology automatically adapts to a wide range of nasal and facial profiles; it is easy to put on with a simple motion and requires no complicated adjustments.

Glider sliding strap (Anti-leak system):
The Glider sliding strap ensures freedom of movement while maintaining a secure fit. The mask pressure remains the same even if the head turns from side to side, limiting the possibility of leaks.

Under-the-chin design (Excellent stability):
The under-the-chin design ensures stability by providing a constant support point and maintaining the mask's fit even as the jaws move during the night.

Efficient air diffuser (Quiet):
State-of-the-art air diffusion system; prevents airflow toward the person sleeping beside you and reduces noise that could disturb sleep.

Silicone seal:
A seal with sealing technology that ensures a soft, smooth feel and sits easily on the face; its satin texture improves the mask's fit and seal.

Crown-style headgear:
The under-the-chin shape ensures maximum mask stability and eliminates the need for a chin strap.

Easy-to-remove strap:
Simply pull the safety cord to remove the headgear in one motion. There is no need to continually adjust the mask.
