Unbeatable comfort is delivered by this device's anatomic shell shape and lightweight style mask. The design also provides a fine seal and a firm grip on the user. Different altitudes do not require air adjustments. The device's circuit connection is stabilized by a hook ring. As the device is comprised of non-PVC materials safety risks are greatly reduced. Direct monitoring and observation is provided due to the mask's transparent construction.
