Very good hydration belt, the double bag is perfect for installing bars, fruit jellies and other supplement for long rides. Personally I use in running the upper outlets 90 '. The bottle capacity is suitable for me, but for strokes longer than 2:30 it gets lighter. The belt fits perfectly in place and is quickly forgotten. Unlike similar products, but sub-brand (which can be found in some stores) the bottles position does not interfere at all the race.
