HydraPak Water Reservoir (1.5L, 2L, 3L) - Hydration Bladder Fits Most Backpacks – High-Flow Bite Valve, Leak Proof, Fully Reversible, and Dishwasher Safe

I've used many bladders and this glorious hiking essential is spectacular. Easy to fill, easy to clean, great flow from the mouth piece which is important, especially when hiking uphill at the Grand Canyon. My favorite part that I didn't realize would be so beneficial is the magnet! I don't need to look down to connect, it's so strong I just wave over my chest and it pulls it into position. It does taste a little like a pool floaty but that'll go away. Best purchase ever!

Great size and functions very well!

This water bladder is very premium feeling with some nice features like a hanging loop for drying and a magnetic clamp for quick storage. I also like that the hose is attached to the sides as opposed to the middle like my old one. Which takes up less depth.Overall, great piece of kit!

500 ml smaller than the original, but fits great in my Dakine bike bag for half the price and better build quality.

I've owned several other hydration bladders before. They're usually in the style with the big giant screw-on lid on one side near the top (see: Camelpak). It's very difficult to get those completely full of water. With this Hydrapak Contour bladder and the zip top, you can fill it completely full of water. There's no wasted space. And it's easier to fill because it's actually the top and not just the side. I'm even confident enough to fill it while it's still in my pack.Leak free. No leaking here so far. Not from the zip top, not from the hose connection, and not from the bite valve. They do say you occasionally have to lubricate the o ring for the hose connection and they do include the lubricant for them, so kudos to them for the transparency, instructions, AND the lubricant. The bite valve locks as well which is great.Sturdy. The material is very sturdy and they were thoughtful enough to add a handle to hold it steady. They also were smart enough to add places to hook the pack up inside your backpack on top of the zip lid. Phenomenal quality.Cleaning is easy. You can turn the thing inside out if you need to for goodness sakes. That ALSO makes it super easy to dry, which is not something I have been able to say about any other water bladder. Ever.I only wish they offered a dust cover for the mouth piece, because those do get dusty and dirty.The magnet clip is a bit of a gimmick, it's not really necessary.

Worked great and perfect for my adventure riding. I have it in my backpack and it’s been super easy to clean and installed. The materials feel’s premium and durable. Looking forward to putting it through some hard riding out on trails and highway. Recommend over cheaper variant’s.

After 25 years using Camelbak products, I reluctantly tried one of these when it came along with a waist-pack I bought. Wow. Their unique folding close mechanism thingy does indeed work well, through many tough hikes and bike rides. No leakage at all. I don't find it any harder to fill (maybe easier!?), and it's dramatically less weight and bulk. Also: it's a game-changer in the ease of cleaning and drying the bladder. (If you ever do that.)I also like the side-mounted hose connector. Why would you want it sticking into the middle of your back? Stuck between the pack and the bladder? Putting it on the edge like this is just logical, and you can flip the bladder so it's on whichever side works best. Why'd it take so long for that to happen?These are a quantum-leap forward in water bladder design and ergonomics. I've switched. You should try it.

Pros: Sturdy, easy to clean, good reservoir designCons: bit valve leaksI am an avid hiker/outdoorsman. Spending many mornings & weekends out on trail a year. I had a reservoir before that would leak all the time, the lining was very thin leading to lots of condensation, and was an all around pain when it was time to clean. I went back to bottles for many years, but was surprised by an acquaintance that was surprised to hear i had leaks and issues with a bladder. So I figured, I had a sample size of one and should try again. So here I am. Unfortunately, this did not pan out. I will say, this is far easier to clean and dry, and the bladder feels very sturdy. The deciding factor came down to the hose. After maybe less than 6 uses, the bite valve is leaking. A slow drip, but after an hour of hiking my t-shirt or down jacket is damp where the hose is hanging (Maybe I bit down to hard at one point?) either way, I had enough at that point. I don’t see myself going back anymore. The bottle design is essentially flawless at this point, easily cleanable, many designs shapes and sizes and many come with filters. Bladders can’t compete with bottles.
