The WIDEPAC™ Hydration System 3L is Source's zero taste & low maintenance hydration bladder. 

Featuring the original Wide Opening Side Seal Top, the updated WIDEPAC™ system makes filling, cleaning, and inserting ice as effortless as possible, while ensuring the system remains 100% leakproof. 

The WIDEPAC™ system incorporates Source’s advanced Glass-Like™ PE film, which is 2000% smoother than standard TPU films, minimizing biofilm build-up and making the bladder virtually self-cleaning. This, combined with Source's GrungeGuard™ technology, ensures that water stored in the WIDEPAC™ stays fresh for days and even weeks without any trace of plastic taste.
