Rated 1 out of 5 by from Tube Kinked Instantly I bought this to replace a CamelBak Antidote reservoir. Although some features of the new designs are improvements, overall, it is worse. The Antidote had flip-out plastic arms that held it open to dry after cleaning it, while this one has no way to keep it open. Worse, the very first time I used it, the tube kinked when I bent it to bring the mouthpiece to my mouth. Now I have to use both hands to drink to keep the kink from closing. I never had an issue with the tube remaining permanently kinked on the Antidote. I have now had occasion to wash the bag twice, and discovered that the baffle has already started to tear away from the bag on one side. Looks like I will have to go back to my old leaky Antidote, since getting replacement warranty parts via the CamelBak website is not yet possible.

Rated 5 out of 5 by from Great Hydration Bladder This bladder is excellent. The new handle and wide opening make it easy to fill. Once filled, the lid seals securely and does not leak. I've used it on several hikes already and have come to appreciate the wider hose that allows for the flow of more water. When done using, the bladder is easy to clean, hang dry, and store in the freezer in order to prevent mold. I highly recommend this product.

Rated 5 out of 5 by from Love it so much! I just finished my first hike using the Crux in my pack and I loved it. I have been using Antidotes up until now and they worked well on the trail, but I always had to struggle to close the bladder after filling it. Something about the way it threaded just always got messed up and I ended up with lots of spilt water. The Crux's closure on the other hand was very easy to use. This got my hike started on the right foot - I didn't waste time (and make a mess!) trying to get my water loaded. I ordered the bite valve cover to go with this and it installed easily. I'm looking forward to many happy years of hiking with the Crux - and I'll be getting rid of my frustrating Antidotes!

Rated 2 out of 5 by from Can't wait to get rid of it I've had this one for 3 years, and I constantly find myself looking for excuses not to take it on trips. Water tasted awful and chemical in it from day one, and continues to do so after the many uses. The lid (at least on the older model, although the new doesn't look that different) is supremely uncomfortable to use. The circular opening and the difficulty of closing it almost always guaranteed water spilling all over. In the past year, it's developed a leak and difficulties closing to boot. Asked someone for a different bladder for xmas and can't wait to get rid of this thing.

Rated 5 out of 5 by from Definite Improvement I have used this bladder only a few times, but so far, it is far superior to the old one I replaced. The wide opening is easier to seal tight, and the valve is ever so much easier to operate.

Rated 5 out of 5 by from Awesome We bought this as a replacement and the first time we used it was hiking the Grand Canyon. This was a major improvement over the last bladder. It is easier to fill and easier in general to use

Rated 5 out of 5 by from Very nice I used it this last week and it worked great when i remembered to unlock the mouth piece. Water flows easy and does not drip by itself. fits in and attaches to my osprey backpack

Is the quick connect valve for this reservoir compatible with the Antidote reservoir fittings? In other words can the tubing and connector be exchanged between the Crux and Antidote reservoirs?

Asked by: Summit Sherpa
The quick disconnect is compatible and can be switched between reservoirs.

Does the tube fit in existing tube holders on the packs now that it is claimed to be larger to allow more flow?

Asked by: Palolojack
Although the tube on this reservoir is larger than other CamelBak reservoirs, it still fits in all of the same packs. The tube size does affect the fit.
