Rated 1 out of 5 by from Dislike the changes I needed to replace my old CamelBak 3L Reservoir because the hook broke. The new one is shorter and wider, so doesn't fit well in my CamelBak pack. The upper portion is too wide when full. I do like the wider opening for filling, but the lid hinges on the top rather than the bottom, so it flops down - getting in the way - when filling. I DO like the locking mouthpiece, but I cannot put the mouthpiece protector on this one. I wish they didn't change the old style.

Rated 3 out of 5 by from Big improvement but lacks accessories Big improvement in the valve and leakage in the cap. However they removed the fold out cleaning bars and there are no accessories for these new Crux Models. The stores sells all the accessories for the old model but don't carry the old model in the stores anymore. Most accessories like the valve cover and thermal regulator for the old version will not fit on this new one

Rated 1 out of 5 by from I had High Hopes I really wanted this to be great Reservoir, I was disappointed! The return to the screw on fill cap was not a good choice it cross treads easy and you don't notice until there is pressures on the reservoir and it then gushes water all over. The shutoff valve is small and hard to operate when wearing gloves. And most of all it does not fit well in any of my existing CamelBak Packs/Daypacks. I only hope that they don't discontinue the Antidote Reservoirs.

Rated 5 out of 5 by from Good quality, safety lock, and easy to clean The REI store staff helped me evaluate the various brands, and I chose this because it was the only one with a shutoff valve on the tube. The large fill/empty port works well for filling, but the design is not quite as easy to drain and clean as some other companies' slide-lock systems. Not a deal-breaker, though. The quality of construction appears to be high.

Rated 3 out of 5 by from New Crux Shape Doesn't Fit All Packs I bought this as a gift to go with a Flash 18 pack. I have previously used the Antidote 3L in Flash 18s with great success. The new shape does not work with the Flash 18 and I had to return it. I'm sticking with the old Antidote shape for as long as possible.

Rated 5 out of 5 by from 3 Liters of Happyness The new handle design is great, easy to hold when filling and handling. No issues with leaking, fits well in my pack. The valve on the mouth piece worked as it should.

Rated 5 out of 5 by from Perfect for lengthy Himalayan hike! I bought this right before taking a trip to Nepal, and it was exactly what I needed! I am grateful for having purchased the larger bladder, because I used every bit of water in the lengthy hike. It seals beautifully, water flows easily, and I will definitely be using as often as I can!

Asked by: Seanymanziel
​If your North Face Recon has a hydration sleeve and a hydration port, this reservoir will fit. Provided that there are no holes in the reservoir and the cap is securely closed, the contents will not leak out.

Will this fit my Rim Runner back from Camelbak...I think its around 20 years old and my 100oz bladder looks noticeably taller and thinner

Asked by: NeilL
Without knowing more about your model of the Rim Runner, we are unable to confirm if this reservoir fits. However, if you have previously used a 3 liter reservoir in your pack, this reservoir will most likely fit as well.
