How much can the Ultra Vest Pro carry?

It is a 10-liter pack. That fits a light shell, food, phone and a spare layer, but not a full overnight kit.

Does it include water bottles?

Yes. It ships with two 500 ml Hydrapak flasks, so hydration is covered out of the box.

The vest is built around the two included flasks. On does not list a reservoir with it, so plan on bottle-based hydration.

On positions it as its pinnacle trail vest, so it is aimed at races and fast, light days rather than heavy training loads.

It carries less than common 12- to 15-liter race vests. Choose it for a minimal kit; choose a bigger vest if you need to carry more layers or gear.

Trail and ultra runners who race with a compact kit and refill at aid stations, and who prefer bottles over a bladder.
