Osprey Hydraulics Reservoir V1

While the reservoir is specifically shaped to integrate seamlessly with compatible Osprey packs, it can technically fit into other backpacks if they have a dedicated hydration sleeve. However, you may lose the stability and specific fit that Osprey packs are designed to provide.

The system includes a small magnet that attaches to your hose and a corresponding magnet that clips onto your pack's sternum strap. This keeps the bite valve secure and easily accessible while you are moving, preventing it from dangling.

At just over half a pound, the reservoir itself is lightweight. You don't have to fill it to the full 3-liter capacity if you are going on a shorter hike; simply fill it with the amount of water you anticipate needing to keep your pack weight down.

Yes, the integrated handle provides a rigid grip point, which makes it much easier to hold the reservoir steady under a faucet or while filling from a water filtration system. It prevents the bladder from flopping around while you are trying to fill it.

The wide-mouth opening allows for relatively easy access to the interior for cleaning and drying. We recommend using a dedicated hydration cleaning kit to ensure the hose and bladder remain hygienic between uses.
