Heartbeat 12 oz Steel Bottle

Study your cardiac rhythms while keeping hydrated! It looks nicer than an EKG pocket guide, and this Heartbeat Flask is functional and aesthetic. Fill it with ice-cold water and take it to the gym for your cardio workout, or top it off with coffee for a long night shift in the cardiac ward.

With a textured design for a unique tactile experience, this flask will keep your drink hot or cold until you're ready to enjoy it.
