## Description

Our latest mil spec reservoir, designed for high-flow, rapid fill and the exceptional performance you'd expect from CamelBak.

Review: Best product ever! - 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.
Review: The highest tech reservoir I have ever owned - 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.

### ⭐⭐⭐⭐⭐ Used this to replace a 2 liter
*by T***R on January 9, 2026*

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.
