Gath headgear is available in sizes Small,
Medium, Large, X-Large and XX-Large (Hat and Fixed Partial Visor
only). Correct fit is critical. It needs to fit snugly around
the head and ears, tight enough not to move around, yet still
be comfortable. Have someone else measure around your head at
forehead level using a cloth tape measure; a metal tape measure
will not give an accurate measurement. In general, front-to-rear
stability is more important than side-to-side.
