Without conventional straps, clips, magnets, and velcro to detach, attach and tangle, AutoLock Headgear from Fisher & Paykel actively prevents over-tightening and discomfort. With AutoFit technology, the headgear automatically adjusts to a comfortable fit with just a single push to fit and a pull to release it. AutoLock Headgear is compatible with all F&P Solo Series masks including the Solo Nasal and Solo Nasal Pillow.
