CamelBak Mil-Spec Crux 3L Long Hydration Reservoir

Camelbacks are one of the best inventions ever. Used them in the military and now in the civilian world for hiking and outdoor activities. Just make sure you ONLY put water in it and clean and dry it out after each use for longevity of the product.

I have owned a Gen-2 Camelbak for nearly a decade now, as well as a variety of wineskins, lightweight water bottles, and waterbags and nothing has compared to the Gen-4. The Crux reservoir features a variety of new kinds of tech that make this water bag stand out. - covered mouthpiece - detachable hose without leaking (unless some water is still in the hose part, that will still leak) - 30 degree tilt for hose detachment so it doesnt interfere with the handle -much stronger, easier to grip handle than the old models - quarter turn "click in" lock. Old camelbaks had to be fully rotated 3-4 times to close - hose covered in fabric to prevent rips and tears - extra thick, internally sealed bladder prevents rips, making the seals the strongest part of the bag all of these aformentioned things make this bag a must buy for rugged, long term use. I am going to be going on a 60 mile hike in the next few weeks and if anything goes wrong I will give and updated review, till then, I highly recommend this bag PS: A little tip, wash with warm water and soap when you first purchase it and it will easily remove the chemical taste from the water. It amazes me how many reviews for this thing say it has a bad taste, they clearly didnt wash it. It takes 5 minutes and it completely neutralizes the issue.

I take longer hikes. I found a bag that I liked and replaced the 2 liter with this 3 liter. I also ordered an insulated hose to replace the bare ones that came with the bag and this pouch. The modular capabilities of everything made the changes seamless. I also go the cleaning accessories that make this bag very easy to clean and dry.

Awesome and well worth the cost. Definitely take a beating w/o leaking or bursting open. Also very easy to clean and fill with ice. There are definitely cheaper options available which for some might be perfect, but if you’re hiking and everything you have and need is strapped to your back and right next to a 3L bag of water, do you really want to trust something that only cost $15 with a name brand you know nothing about not to rupture and soak everything you have? I’ll pass on that noise which is why I spent extra and got this. In all fairness I’ll never know if I could’ve went with the cheaper one or not but my gear didn’t get wet and that’s all I care about.

Easy to clean and take apart and easy to fill, while drying roll up the hose and put it in the mouth of the bladder to keep it open so it dries fully, but the rim can hold some water, just make sure it dries fully so it is a safe water source. Fits well in the CamelBak mil spec crux.

great replacement for older style camelback backpacks like mine i have an old 2009 H.A.W.G model backpack it never had a bladder the whole time i owned it. and this one fit great, would highly recommend if you need a replacement.

It works really well does add a lot of weight to an already heavy pack but it was worth it water lasted all weekend

I have been very disappointed with the quality of this Mil-Spec reservoir. The Mil-Spec design is slightly different than the standard Crux reservoir, with the bite valve separated from the (insulated) tubing system by a connector that is exposed to the elements. This results in an effectively useless reservoir in winter weather (e.g., while hiking or skiing) because the exposed component freezes near instantaneously when ambient temperatures or wind chill dip below freezing. I've also had the hanging clip break off the bag after less than two months of use. The "Mil-Spec" label might allow them to charge more for this item, but the craftsmanship is subpar. If you need a reservoir for use in colder climates, I suggest you look elsewhere.
