Osprey Hydraulics 3L Reservoir

— Show original

Really easy to use and seems high quality and durable. The sturdy technical parts and magnetic fastener make it easy to find a suitable resting place on the backpack straps. Works well in the mouth. It was a little hot to open the filling opening the first time, as it felt like something was tearing or falling apart, but the blacksmith was only held together with strong glue. So it opened well and was easy to fill and place in the backpack (both of the ones I use are Osprey's own older backpacks)

Works well and doesn’t leak. Magnetic tube holder is a nice touch.

A good hydration bladder for your backpack.

A quality product with well-designed details, such as the magnetic attachment and the hose removal from the reservoir. The reservoir is quite difficult to fit into an Osprey backpack, although the support structure keeps the reservoir in place better than many others.

Excellent bladder and goes well with Osprey's Aether rucksack.

Another 3l Osprey bladder for our household. This model is slightly improved from the already good one. Pouring water is easier thanks to the handle and maybe filling with natural water, I haven't tried that yet. You can easily get hoses and spare parts for these.
