Choose the Correct Fit
Check that the liner fits comfortably beneath your Milwaukee hard hat or helmet without changing the required suspension fit.
This is a fabric comfort liner. Continue to use the head protection and other PPE specified for the work; the liner has no stated helmet rating.
Installation & Care
Put the liner on smoothly, then fit and adjust the head protection as instructed. Avoid folds that create pressure points or disturb the suspension.
Follow the garment’s care label. Keep it clean, let it dry and replace it if the stretch, seams or fabric become damaged.
