Ergonomic design permits perfect fit on any face shape. Minimal face contact more comfortable and less irritation. Large breathing chamber allows longer use, more comfort and better performance by the user. Excellent inhalation/exhalation performance eliminates requirement for valve and therefore potentially dangerous valve leakage. Enhanced visibility for users wearing goggles/specs.
