Have you purchased on of the new Low Pro Hats and somethng doesn't seam right.
Check out the hat.
Get a regular MSA Comfo and a Low Pro Hat and weight them,
Low pro will weigh more.
Put one of the Low pro Hats on your head and get a leveler and have someone mark the height of the Low Pro...same height if not more.
One reason I never tried to get a low vein hat certified is because the a real low vein will not pass .
