The UTMB World Series has announced an exclusive three-year partnership deal with up-and-coming trail running brand Aonijie. The Chinese brand will be the official hydration pack supplier for all UTMB World Series events.
Launched in 2011, Aonijie has made a name for itself in the Asian market with trail running equipment such as running backpacks, waist packs and headlamps. It will launch a dedicated line of UTMB hydration packs as part of the deal, which it says will be designed to withstand the extreme conditions found in the Series' 218 races across the globe.
