The V1 Viking Earmuff offers a multi-position headband which allows the wearer to select how to wear it - over the head, behind the head, or under the chin. It now incorporates the patented Air Flow Control technology. It is a good alternative to cap-mounted earmuffs; it can be worn with hard hats, faceshields, respirators, and other personal protective equipment. The non-deforming headband features include inner-ventilation to minimize pressure on the head, and it can withstand rough treatment in the workplace. The snap-in ear cushions make replacement quick and easy. The Viking comes with a headband strap for better positioning when worn behind the head or under the chin. The dielectic construction is suitable for all workplaces, especially electrical environments. The V1 Viking Earmuff has a NRR rating of 25. Sold in cases of 20 earmuffs.
