    Stay hydrated.

    Osprey doesn't mess around when it comes to keeping you comfortable on the trail, and that's evident in the design of its Hydraulics LT Hydration Reservoir. Made with twin-welded chevron baffles, this reservoir limits sloshing, stabilizes water, and maintains a flat profile in your pack. Osprey equipped the Hydraulics LT with a convenient Slide-Seal closure for easy-filling at the kitchen sink or spring, and the magnetic bite valve ensures you don't loose any water until you're good and ready to wet your whistle.

    Have questions about this product?

    Seem excellent!

      Can’t wait to use this bladder with my new Lowe Alpine Aeon 27L ( I got the valve cover also) Can’t beat backcountry with their free two day shipping over $50, it’s so quick! I ordered the back pack on another website 2 days before these and they arrived before! Lol

      Great Bladder but...

      • Familiarity: I've used it once or twice and have initial impressions

      I love the features on this bladder. The grip handle is very convenient and I like the shape of the valve. The only issue I have is that I put this in to a hydration vest (Nathan VaproKrar.) Which is, in typical fashion, thin and almost tshirt-like. The slider is tapered in the middle and flares out on each end - in to a point. Because of how thin my vest is those points dig right in to your shoulder blades. I have to lay a tshirt between the top of the bladder and my back to prevent it from poking me during my long runs. This bladder will probably work perfectly for traditional hydration packs since the padding between your back and the bladder seem thicker but not so much for a vest.

      Good little bladder

        The bladder is pretty good; holds the right amount of water and the closure is nice to work with. My only complaint is that the value in the tube (not the mouthpiece) is a little hard drain, and I worry that if I don't it'll get moldy.

        Best hydration bladder out there

        • Familiarity: I've put it through the wringer

        Call me an osprey fanboy, it doesn't bother me! Everything I've used from Osprey is very well engineered and thought out well, including this bladder.

        The bladder has a hard plastic backing so it won't collapse as you use water, an easy to hold handle for filling, and an easy to use fold down seal, with sliding cover. The handle, and folding top make it easy to pour into a cup or pot. The hose also has a magnet to clip to your chest strap, so it's easy to find!

        I love this bladder so much that I've purchased two as gifts as well

        Great bladder

        • Familiarity: I've put it through the wringer

        The Osprey water system is my favorite with their magnetic system that keeps the water tube connected to the front of the back. Plus, the bladder opens all the way, which makes cleaning and maintenance much easier.

        Awesome Bladder

        • Familiarity: I've put it through the wringer

        This bladder has been my trustee hydration companion for years. It's the perfect size for my Osprey Daylite Pack. It doesn't add too much weight, but holds the perfect amount of water for a short day hike. The side-seal closure is great and I never have to worry about any leaks. I have to say, the magnetic attachment is my favorite feature - so easy to snap on and off. The rubber mouth piece will wear down over time, but a replacement can be purchased and easily reinstalled.

        Get this

        • Familiarity: I've used it several times

        If you don't have a bladder, I highly recommend you get this one. It's super easy to use, no leaks, pretty easy to clean, and does the job. I got this bladder to compliment my Osprey Daylite Pack and I couldn't be happier.

        Better Than The Others

        • Familiarity: I've put it through the wringer

        I'm a big fan of the slide-seal closure! Makes filling and cleaning the bladder much easier than the competition. A great addition to any Osprey pack that has room for a bladder. I use this bladder in my hydration pack while going on longer mountain bike rides and have no complaints after riding around with this bladder for thousands of miles.

        2.5 L

        • Familiarity: I've used it several times

        I bought this before hunting season for my pack, my hunting partner buy a platypus. He had so much problem rolling up the top an putting the clip back on, I walked up to water hole filled folded slid top back on an was off before he new what was going on. I would recommend 100x over!!

        Might End Up Replacing My Platy

        • Familiarity: I've put it through the wringer

        I really do love this bladder. I went with the smallest one they make for short quick backcountry trips. I used it in my UD trail running vest, my climbing pack, and in one of my lumbar hip packs as well. The hose detach is farther up the bladder hose than most, making mid adventure refills a breeze. Also, the bladder open and close zip design is one of the best on the market.

        Plenty of water
