Osprey Hydraulics 2L Reservoir

No caps to open, lose, or have leaking! A slip-resistant backing keeps the reservoir in place nicely. The mouthpiece needs to be bitten on to release liquid, so this is a bit funky. But in creating this type of mouthpiece, you are truly able to get every last drop of fluid—a suction is created.

I used this bladder on my Rim2Rim hiking trip, and it did not disappoint! I would recommend this hydration bladder!

Pros

  • No leakage
  • No shifting
  • Easy to refill

Cons

  • Have to get used to biting the mouthpiece to obtain fluid

I purchased the 2L Hydraulics bladder. In temperatures of 103° during the day, this size seemed ideal. I was concerned to minimize the weight of my pack on the Rim2Rim backpacking trip, so I decided the 2L combined with one 32 oz Nalgene (filled with a Gatorade type product) would provide enough for my hydration needs.  In actuality, the Nalgene probably wasn't necessary.

The bladder's hose was long enough so there were no issues being able to access in times of thirst. The hose also has a quick release snap on/off right at the top of the bladder, making it effortless when refilling.

I've had Camelbak bladders and they all had a tendency to leak (for me, at least). The Osprey has a fold-over design with a guided clamp to keep the fluid from soaking everything you wished to keep dry in your pack. The back of the bladder is semi-rigid, so this keeps the bag from folding over or swishing around in your pack.

The only thing funky was having to bite on the mouthpiece to release fluid. It took a bit (no pun intended) of time to get used to, but I've adapted. I believe the reason for the bite mouthpiece is it creates a suction, so I literally got every last drop of fluid from the bladder. 

The cost was in line or a couple bucks less than the Camelbak 2L, but definitely outperformed the Camelbak.
