CamelBak Crux Water Reservoir Hydration Bladder

Edit, February 2026: So about 4 years later, the cap and seal somehow broke off. Now there's a hole in a bladder bag and the cap and thread are just separated from the bag. Not terribly upset because it lasted about 3 years and change with regular use. Original, November 2022: I purchased this about three years ago and have been using it ever since. I tend to drink a lot of water when I'm outside doing any kind of strenuous activity -- hiking, rock scrambling, running. This three liter reservoir is a great option to swap out the included smaller 1.5L and 2L bags that come with the packs that I buy. Very long hose ensures that you can use it with small day-packs, hydration vests, and backpacking backpacks, and nozzle works okay for sipping. Some people that have an issue with sealing and leaks -- I only had that problem in the beginning, but it's mainly because I wasn't sealing it right. You just have to make sure the cap is on securely before you start turning clockwise to seal it shut. If you do this, then you'll get a good and secure seal each time.

As always, this brand doesn't disappoint. Excellent product, works perfectly and never leaks.

Great. I use this for rucking. It’s easy to get a good amount of water per “sip”, and it holds a little over 3L. The material is good, it’s a thick-ish rubber thats smooth but not slick. It doesn’t leak. The cap comes on and off easily, you just twist it the same as any twist-lid, but it won’t undo itself. Rinse the thing out, including the tube, before actually using it. I say that because there’s a hint of a chemical taste at first, if you don’t. Overall great purchase, you won’t be disappointed. If you’re looking for a 3L Camelbak, id choose this one

Works great overall just be aware the blue ring on the cap can come loose, which causes leaks. Once it’s securely back in place, though, it seals perfectly and doesn’t leak at all.

I needed a replacement because my other one was old. Works great.

Exactly as advertised - Fit my old Camelback backpack. Used right away and it was great.

Replacement and upgrade for old original👍🏽

I bought this product after reading mostly positive reviews - but some reviews said it leaked, it was hard to fill completely and the water tasted bad. The only problem I had with leaking was the one time I didn't get the cap on right. However, I always turn it upside down before putting it in my bag to check for leaks. There's a trick to getting the cap on correctly: when you put the cap on first spin it slowly counter-clockwise like you're unscrewing it until you click a "click." That sound is the threads engaging and lining up. Then screw it clockwise and tighten as normal. I agree that it shouldn't require a "trick" but once I figured this out I can quickly and easily get the cap on correctly. The hose connects with a solid "click" and I've had no leaks from that connection. The second issue I've seen in reviews is that it's hard to completely fill, and this is true if you try to get every last drop possible in it. However, I questioned how much water this actually holds so I completely filled the reservoir and poured it out into my 2 liter measuring cup. It held about 2.2 liters. So it is hard to put 2.2 liters into a 2 liter reservoir, but it's easy to fill to the 2L advertised capacity. The other issue is the taste, and if you put water in it brand new without cleaning it, it will taste like rubber. So I washed mine with warm water and a little dish soap (and ran some through the tube) and thoroughly rinsed it. I spent 10 minutes doing this 1 time and the water tasted completely normal after that. If you leave water in it for over 24 hours (especially if partially filled) then you'll get a slight aftertaste. If you're looking to store water for several days without any change in taste, then this product probably isn't for you. Two things that would make this better are to include a sleeve option for the tube. I've got a green/brown bag and the bright blue tube just doesn't look good against it. Also the hook at the top of the reservoir (used to hang inside your bag) is shaped like a T and that works great in my bag, but my wife's bag has a velcro loop. To secure it in her bag we'll have to rig a string through the T hook and the loop in the bag. Finally, check the dimensions before ordering your size. The measurements showed it would be a tight fit in my bag and it is, but it works fine and I'm glad I got the larger size. The measurements in the specs are accurate with the bag full of water. Bottom line, I liked this enough to buy one for my wife.

Muy buen repuesto

I have bought multiple Cambelbak bladders over the last 10 years and they keep me very satisfied. These are by far the best reservoirs on the market. The handle makes it easy to fill and close the opening. It is made from sturdy material and the bladder itself will keep the water pretty cool when stored in a backpack, even on hot days. I also have an insulation bag, but I never use it. When cycling in 32 degrees Celcius, that's 89F for you imperial speakers out there ;), it will keep cool in the backpack throughout the day. It never leaked when I used it. I can really recommend this bladder.

Indispensabile secondo me per lunghe uscite in montagna! La praticità di bere senza ogni volta cercare la borraccia o dover togliere lo zaino! Zero retrogusto di plastica, semplice da pulire grazie al tappo ampio, soddisfatto

I’ve used this CamelBak hydration pack twice so far, and I’m very happy with it. It doesn’t leak at all, it’s very easy to use, and it arrived very quickly. The drinking nozzle is also very well designed—it locks securely and is easy to use. Great product!

Sacca idrica top di gamma. Ho acquistato la camelbak da 3l adatta soprattutto per i trekking più lunghi ; il materiale non altera in nessun modo il gusto anche quando sottoposto a stress termici (caldo estivo/ freddo), l'erogatore è molto pratico e comodo, fornisce un buon apporto d'acqua. Punto di forza è sicuramente il tappo, permette di riempire la sacca e chiuderla in piena sicurezza senza che vi siano perdite. Assolutamente consigliata.
