The 8 Best Small Water reservoirs (2023 reviews)

If you want nothing short of the optimal reservoir for your regular usage, this osprey small water reservoir is certainly a wise investment. The little magnet that keeps the tube on your chest strap is clutch. It has the stiff back and easy to insert back into an Osprey Zealot. It comes with twist on/off and offers an ergonomic drinking angle and great flow. The suction tip has a twist seal as well to prevent bump dripping. It is made for light and fast activities where weight and balance are critical.

The magnetic nozzle attachment is perfect, the large opening top is nice for filling from any water source, and the disconnect of the tube from the bladder lets you take it out without pulling the tube out without pulling the tube out. The magnetic snap in front is a nice touch too. It allows for easy loading into internal hydration sleeves.
