Hydraulics LT Lightweight Water Reservoir / Hydration Bladder (1.5-2.5 Liters) - Prior Season

This is a really great hydration reservoir. It is easy to clean, easy to put together, and fits my Salomon running vest perfectly. There was a heavy plastic taste the first few times I used it, but I read online to squeeze fresh lemons in the pouch, add water then freeze overnight. After I did that, it worked great, and the plastic taste was gone. I can tell this is going to last me quite some time.

It’s my 2nd bag (I couldn’t find the first one which I got about 3-4 years ago and used extensively, so bought another one). Both bags were/are great! No leaking, no ruptures - served great during my Yosemite backpacking trip!Regarding water taste - you may feel a little plasticky taste at the beginning, but the longer you use it, the less it’s present. The former I would say was already without any aftertaste. I also had CamelBak and I think the Osprey has less problem with the taste…Wait for the right price, which should be about $38 or less…Black Friday price was $34.50 and Apr10 2025 so far the lowest price I have seen $30.77

Exactly what i needed, it's perfect for my 38l.

REALLY! About 4 days ago I woke up thinking there has to be a better water bladder design. Every time I fill up my Humpback (you know the one) bladder it swells up as big as my leg and takes up half the pack. I thought to myself, what we need is a bladder with an internal panel that makes it keep it's shape. I thought to myself of the $$$millions that I would make and how adoring fans would stand in line just to thank me. Then I looked on Amazon.RATS! Right there before me was this Osprey 2.5L bladder designed just for me. It does not hurt that I also have an Osprey pack. Seriously, this may be the absolute best design that I have seen. The V that you see is two "welded" in panels that keep the bladder from ballooning into a sausage. When fully filled it is about 2" thick and should easily fit any pack designed to carry a bladder. The hose can be easily routed left or right as required by your pack. It also has a quick disconnect inside the bag that allows the bag to be removed with out having to reroute the exterior part of the hose. The magnetic clip to keep the mouth piece in place for easy access is simple genius.I could go on about how easy it is to fill etc etc etc but instead I will say that if I had build my own bladder it is pretty certain that it would look and work a whole lot like this one does. Of course, I will miss my adoring fans but at least I did get a great bladder and did not have to make it myself. Absolutely recommend this.

I bought one for my husband and then replaced my old one (different brand) with the same reservoir.Likes-The bite valve works well.It comes with the magnets.It stays flatter than some due to the internal baffles.It's easier to fill and clean and easy enough to position so the tube can come over either your right or left shoulder.The slide on sealer worked well and my husband had no leaks. (I just opened and cleaned mine but it seems at good. A long hike will test it better.)It feels lighter than my older one that also holds 1.5 liters although I didn't weigh them both.Dislikes-The packaging. The packaging. The packaging. I have arthritic hands and cutting oven the (plasticized?) cardboard and removing the hard plastic cover on the bite valve took forever and was painful. Do better, @Osprey!!The packaging.

Works great. I wasn't sure about the type of closure - I'm unfamiliar with it and have heard many reports of leaking, however I haven't had any issues. I did buy a cap for it which isn't the best but I prefer not having it get drug around in the mud. First drink every time (and it was drained and dry before use) always tastes a little funky. Then I don't know if it doesn't taste anymore or if I'm used to it, but I haven't really noticed any other weird tastes after that. Capacity is also perfect.

Great product to replace your old nasty Osprey bladder. Easy to change and it came with a new magnetic attachment point for your pack. I used this with my Osprey pack but it would likely work with other packs.

I had no problem with a funky taste, just rinsed a couple times. The top fill is a bit tight but it is also made for pouring water out, like into your cooking pot. I like the mouthpiece, you can leave it unlocked, use the magnetic holder (which is such a great idea!) the more you bite on mouthpiece the more water you get. I did have the quick release that’s towards the top of bladder come apart but it was as I was taking it out to fill. Yesterday it was squeaking somewhere in that area but I never figured out what it was. Annoying and I hope it doesn’t become a normal thing
