MSA V-Gard Slotted Hats are now available in all colors; non-slotted hats have been discontinued. All existing V-Gard Helmet non-slotted hat part numbers have been retained for slotted hats. Sound Control SH® Ear Muffs are also available for use with V-Gard Slotted Hats. These earmuffs allow users to retain the dielectric rating of the V-Gard Helmet, as the muffs simply fit in the slots; no drilling required!
