Vert Flask 150mL
The reusable flask will save thousands of gel packets from entering landfill or trashing the environment. The flask fits 5 servers of Vert enough to fuel you for 2.5 hrs. You don't have to put 5 in it though. It still works well with just 1 serve of Vert.
The flask design is the culmination of many runs and rides. Small enough to fit in a running belt, large enough for 5 serves, able to be operated single handed, won't leak in your pocket.
