Official UTMB World Series Partner Vest
Built for the demands of distance trail running, the Aonijie 8 litre hydration vest delivers race-proven performance for efforts up to 50km. Featuring the official UTMB World Series logo, this Mont Blanc series vest combines intelligent storage, dynamic fit, and exceptional breathability to keep you moving fast through technical terrain.
Designed for Speed and Endurance
At just 200g (size L), this vest virtually disappears on your back while carrying everything you need. The breathable mesh back panel actively wicks moisture to prevent overheating, while the stable compression system keeps your load secure without restricting movement. Two 500ml wide-mouth soft flasks sit in easily accessible front pockets for quick hydration without breaking stride.
Intelligent Storage System
Multiple compartments keep essentials organized and accessible. Front pockets include dual soft flask holsters, two plunge pockets, a zippered security pocket, and narrow shoulder pockets for gels and nutrition. The rear features zippered and plunge pockets plus through-pockets for larger items. Pole attachment points on either shoulder allow you to stow trekking poles in a quiver (available separately), when the terrain demands hands-free movement.
Note: Not compatible with hydration bladders. Wash before first use.
