Stretchgear Headgear involves a special elastic headgear segment that can maintain an equal mask force when the head is tilted upward or downward, keeping constant air pressure in your mask.
Under-Chin Design results in a stable mask fit by providing a constant point of reference and maintains the optimal seal even if the jaw moves during the night.
Crown Strap complements the under-chin design to promote greater stability and eliminate the need for an additional chin strap.
Efficient Bias Diffuser provides an advanced air diffusion system that prevents air from blowing onto you or your sleeping partner while at the same time reducing air noise that can disrupt a peaceful sleep.
Premium Frosted Silicone Seal provides a soft, smooth feel on the face while at the same time, optimizing the seal for consistent pressure.
Easy-Release Strap provides a one-step process for removing the headgear from the mask. Simply pull the easy-release cord when it's time to clean your mask. No need to re-adjust the headgear when reassembling.
Hidden Strap Release enables the removal of the headgear from the frame for cleaning, then reassembling without the need to re-adjust the headgear. Simple, time-saving, efficient.
