The Finis Cardio Cap is a swim snorkel accessory designed specifically to fit the Adult and Junior Swimmers Snorkel and will restrict the amount of air coming into the snorkel to help increase your lung capacity and cardiovascular conditioning.  Using the Cardio Cap regularly, will help your muscles to work better when your oxygen levels are low by replicating higher altitude workouts.
