Speedglas Complete head harness to suit Speedglas 9100 Series Welding Helmet (part number 533000).

The 3M Speedglas Welding Helmet Series 9100 features a highly adjustable, comfortable head harness. The outside of the human head is lined with nerve-endings, arteries, and acupressure points; applying pressure to some of these spots actually makes a person feel fatigued. The head harness specifically avoids these vulnerable areas. It provides multiple adjustment combinations so you can "tailor" the helmet to fit your personal preferences and comfort setting. Less pressure - and a perfectly-adjusted, personal fit - means more comfort, all day long.
