Ward Smelling Salts worked with both professional and amateur hockey teams to develop the first smelling salt bottle for cold conditions. Unlike other smelling salts it won’t lose its potency on cold ice rinks. Smelling salts work by causing a sudden release of adrenaline that allows you to push your athletic performance beyond anything you've experienced. Ever wonder what hockey players are smelling on the bench before they come onto the ice? That's smelling salts! The majority of professional strength athletes, football players and hockey players use smelling salts! Ward Smelling Salts are shipped "unactivated" so they do not lose potency.
