The Osprey Hydraulics LT Bladder is a fully-featured bladder with many functions at a decent price. It stands out for its longer flip-top closure, built-in handle, extended quick release hose system, and magnetic bite valve that always keeps water close at hand. It is straightforward to use and compatible with most backpacking and running hydration packs. The handy handle helps you maximize your fill by holding the bladder horizontally.
We love the longer collar on the flip top, making it easy to collect and share water. It comes with a magnetic tube clip that attaches anywhere on the tube; this clip can also be removed and used for other packs that don't come with a tube clip. Even though this bladder has many great features that we loved, it fell a little short when compared to the CamelBak Crux Reservoir, our Best Buy winner. The Crux is easier to fill and a little lighter. It also did not harbor any plastic taste out of the box.
Another key comparison is the Osprey Hydraulics that features a robust and sturdy backplate with all the same features of the LT. It's a little more expensive, a little heavier, but offers a stiffer design that is more durable and easier to stuff into filled backpacks. Overall, the Osprey Hydraulics LT is a great lightweight and featured reservoir at a great price.
