These are great for really long training days and racing, where you need to take in a lot of calories. The container is a good size and fits comfortably in a rear jersey pocket. The big advantage of these over a flask of Gu or other gel, is that the EFS has a lot of electrolytes to help stop the cramping.
Pros: Will keep you fueled for several hours.
Cons: Expensive.
