Created for athletes who push so hard that they can’t easily take in enough calories to perform at their best. This product has been tested for over 20 months with the world’s greatest athletes, including Gold Medalist Triathlete Gwen Jorgensen and the EF Education First Pro Cycling team. It has allowed these athletes to drink their fuel on some of the longest and most intense events in the world when they can’t eat real food, without causing gastrointestinal distress.
