Helmet Fresh spray removes the odors associated with helmets and other sporting equipment. Simply spray the inside of your helmet after you take it off, and let it air out. Helmet fresh attacks bacteria and mildew - the source of odors - leaving a fresh, clean smell. It is not scented so it does not mask the odors, it eliminates them. Available in a handy 4 oz. spray bottle. One bottle can easily keep your helmet smelling like new for an entire race season.
