Use the LIFT Safety DAX sizing and fit information below to help select the proper fit. DAX hard hats use an adjustable ratcheting fit system rather than traditional small, medium, and large sizing.
LIFT Safety DAX Sizing
LIFT identifies the DAX hard hat as one size fits most, with an adjustable fit range designed to accommodate a variety of head sizes.
| Hard Hat | Head Size | Head Circumference |
|---|---|---|
| DAX | 6½ – 8 | 52 – 64 cm |
Fit Note: The DAX ratcheting fit system allows the suspension to be tightened or loosened for a secure fit. Adjust the suspension until the hard hat feels stable and comfortable without excessive pressure.
How to Measure
Head Circumference: Wrap a flexible measuring tape around the widest part of your head, passing just above the eyebrows and ears and around the back of the head. Keep the tape level and comfortably snug.
Check the Fit: Compare your measurement to the 52–64 cm DAX fit range, then use the ratcheting adjustment system to secure the hard hat comfortably on your head.
