Evora's unique floating seal engages to wrap around the nose providing a flexible, gentle, comfortable seal at the base of the nostrils. The cushion's integrated stability wings work together with a lightweight, flexible breathing tube and 360º swivel, to keep the mask in place without tugging or pulling as you shift, roll and move during sleep. Minimal Contact - The silicone material of the cushion sits softly under your nose to provide a comfortable fit during sleep and reduces the risk of skin irritation through contact. This is most beneficial if you suffer from sensitive skin or have allergies to certain material. If you are a side sleeper or an active sleeper, the Evora is the mask for you and with a 30-day satisfaction promise, you will receive a full store credit if you are not completely satisfied! Sleep Quietly - Laser-drilled exhaust holes in the mask frame minimize noise and draft as you sleep. In turn, this ensures you and your family can sleep peacefully throughout the night. Freedom of Movement - These compact nasal seals rest gently under your nose to create a comfortable, unobtrusive fit, while the flexible short tube keeps your mask in place. The stability wings on the sides of the cushion maintain your seal and reduce the risk of mask leaks while the floating seal wraps around your nose with minimal contact. Move freely as you search for the most comfortable sleeping position without the hassle of losing your mask seal!
