Mace is not a product, but a brand name. Mace tear gas has several advantages over pepper spray, including its power to spray up to 18 feet. Mace tear gas also comes in a gel or a foam that sticks to the attacker and cannot be wiped away. While the assailant tries to wipe the offending foam away, they cover their hands and arms with UV dye. Mace makes self defense sprays that are legal in Michigan and Wisconsin. Mace tear gas gives the jogger or other solo victim the choice of defending themselves before they are attacked.
