Wise Running Bag 333 (12 liters)

Designed for long days on technical terrain. This ultra-trail vest feels extremely light on the body and stays close to the torso without moving in a bothersome way. Especially during descents and fast sections, you notice how little the vest bounces, even when fully loaded.

Plenty of accessible storage without stopping. The biggest advantage lies in the smart layout where Nutrition, layers and mandatory equipment remain quickly accessible while running. During ultras or races with many changing conditions, this makes a noticeable difference in rhythm and focus.

Stable under load. The angled flask pockets hold soft flasks firmly in place without creating pressure points on the chest. Even when you become fatigued or technical terrain becomes more difficult, the vest continues to feel calm and predictable.

Choose this vest if you want to run efficiently and stably during long ultras. Not if you are primarily looking for a simple vest for short training runs or local loops.
