The Mirage FX For Her is incredibly streamlined and light-weight (less than 2.5 ounces with head-gear)! The mask's frame is strong enough to stabilize the mask, yet soft enough to accommodate movement during sleep. The mask's Spring Air cushion is coated with soft-touch frosting to improve comfort; and Soft-Edge straps are flexible and breathable with rounded, seamless edges to reduce strap marks.
