Our Analysis and Test Results
The Osprey Hydraulics LT comes with a few more bells and whistles than most bladders. It's easy to use and compatible with most backpacks.
Ease of Use
Simply put, this bladder is easy to use. The bite valve is simple, doesn't leak, and provides ample water flow with minimal effort. The twist lock mechanism is harder to use than a simple switch, but if you don't like it, you can switch it out, as this model is compatible with many other valves and tubes. We like the magnet it comes with as well. It easily connects to the tube (anywhere you please) and you can choose where to attach it on your pack. We prefer it on our chest strap while running and hiking.
Another cool feature is the location of the quick release hose, similar to the Osprey Hydraulics. Instead of the quick-release being at the base of the bladder, it falls about halfway up the hose. This is advantageous when you want to disconnect your bladder without digging through a pack full of gear. This is especially useful when we were on the move or out backpacking.
Ease of Care
This bladder is quite easy to clean, but not as convenient as other flip top varieties. The opening huge allows you to easily get a brush inside, so scrubbing inside isn't too hard. That said, when trying to flip it inside out, our efforts were deemed useless because of the plastic handle and hose connection. Because of this, we opt to simply rinse it out and allow it to dry. Afterward, throw it in the freezer to kill any unwanted and lingering bacteria.
Ease of Filling
Similar to other HydraPak manufactured models, this bladder is quite easy to fill in both deep and shallow environments. It stands out for its attached handle and the extended tongue that provides easy filling in all situations!
Collecting water from trickling streams is a cinch, and filling in shallow water fountains is easy too.
Quality and Durability
We had no issues with leaks in the bite valve or pack after our months of testing. It is made from a TPU film that is quite durable but not as puncture resistant as thicker filmed options in this review.
Weight and Compressibility
A little heavier than other flip top versions, this 2.5L bladder weighs roughly 6.15oz. Because of its extended tube that does not detach at the base of the bladder, it is not super packable.
This is a great all around use bladder! Take it skiing, hiking, biking, and more!
At only $34, this is an inexpensive bladder with great features and performance.
If you seek a lightweight but high performing bladder with all the bells and whistles, this is a great option. Take it running, hiking, or camping…whatever you please!
