Glider™ Strap The sliding Glider™ Strap provides freedom of movement while maintaining a seal. Mask force remains equal when the head rotates from side to side, minimizing the occurrence of leaks.

Premium Frosted Silicone Seal This seal technology has a soft, smooth feel to slide onto the face, and its frosted texture optimizes the mask seal.

Efficient Bias Diffuser With Material Filter or Maintenance Free This advanced air diffuser system prevents air from blowing onto the sleeping partner and decreases noise that could potentially disrupt sleep.

Under-Chin Design An Under-Chin fit provides stability by providing a constant point of reference and maintains the seal even with movement of the jaw during the night.

Crown Strap Complements the Under-Chin Design to maximize stability and eliminate the need for a chin strap.

Easy-Release Strap Simply pull the Easy-Release Strap for one-step removal of headgear. No ongoing headgear adjustments required.
