The Aonijie MB-12L Mont Blanc Vest is designed for ultra-distance trail running where carrying capacity, accessibility, and weight all matter.

With a 12-litre capacity and multiple storage zones, it provides space for mandatory gear, nutrition, and hydration without compromising on fit. The vest comes standard with two 500ml soft flasks and is also compatible with a 1.5–2L hydration bladder, giving flexibility depending on race or training needs.

The construction uses lightweight, stretch materials to create a close-to-body fit that minimises bounce while allowing freedom of movement. With a high pocket count and accessible front storage, it is built for long efforts where efficiency matters.
