The Ultimate Direction 1.5L Reservoir is a high-performance, lightweight hydration bladder designed for running, trail running, fastpacking and hiking where you want adequate hydration without unnecessary weight . With a 1.5-liter capacity , it's perfect for shorter to medium-length workouts, or for those who combine reservoirs with front-mounted bottles.

The reservoir is built with durability and ease of use in mind . The wide opening makes filling, cleaning and turning easy, while the leak-proof construction lets you focus on the adventure – not your gear. The updated design includes universal controls , an easy-open mouth and a convenient hanging hole for easy drying.

The flexible, kink-free drinking hose (36”) made of durable TPU drapes naturally over the shoulder for a smooth flow. The Plug-N-Play™ connection allows you to quickly disconnect the hose for refilling or cleaning, and the high-flow bite valve is self-sealing to eliminate drips.

The reservoir is 100% BPA and PVC free , can be frozen or filled with hot water up to 60°C , and is covered by Hydrapak's Beyond Lifetime Guarantee .
