## Description

The CamelBak Long Neck 3L Hydration Reservoir is built for users who need a proven hydration solution compatible with legacy tactical and military hydration carriers. Designed to integrate with standard US Army hydration systems, it supports continued use of Long Neck‑style loadouts in demanding environments. Constructed from radio‑frequency welded polyurethane, the reservoir delivers durability and elastic performance under heavy load. A classic Big Bite Valve provides high‑flow hydration with a self‑sealing design, while the HydroLock lever allows one‑handed control of water flow, even when gloves are required. A protective drink tube sleeve helps reduce abrasion and UV exposure during extended use. Featuring HydroGuard technology embedded in the reservoir and tube materials, the system is designed to help inhibit the growth of bacteria on interior surfaces, supporting easier cleaning between uses. Compatible with Long Neck hydration carriers and select legacy CamelBak packs, this reservoir reflects CamelBak’s long‑standing expertise in field‑tested hydration systems built for reliability, durability, and mission continuity.

Review: This is amazing - I mainly bought this for an airsoft battle in the next couple of days. It arrived just the day before and it performed splendidly. It's able to hold a ton of water and is able to keep it cool even on hot days. It's skin is also extremely tough that it's able to withstand mulitple BB shots and still not leak. I recommend you first wash the bag before use thou and when in use to first take a couple of mouthfuls and spit it out because the water in the tube is warm and probably dirty.
Review: Good replacement bladder - Great fitting replacement.

### ⭐⭐⭐⭐⭐ Good replacement bladder
*by M***L on July 17, 2026*

Great fitting replacement.

### ⭐⭐⭐⭐ Worked great through Yosemite
*by T***B on August 11, 2015*

I used this with my hike through Yosemite Valley. It did well. It held a lot of water. 3 liters is a good amount of water. Unfortunately for me, it added so much weight to my pack!!! I would probably only fill half of that and just pump water from a water source. But, getting back to the product. It did very well. Easy to fill. Although I don't like the opening to pour water. I think what would be a great design is for the opening to extend from the actual bag. Sort of like the old water bottles. Then you can fill it all the way. Right now, you can only get close to the opening without spilling. Even though the bag didn't leak, I feel that there should be some sort of rubber seal that can create a tight seal because the current cover is plastic and it screws onto plastic threads. Plastic on plastic always has the potential to loosen up. Especially in a pack. I also like that the product comes with a special plug that you can use to put on at the bottom. I did that so that I can fill it up without having to carry the reservoir. Overall, it's a nice bottle. Fits in my pack nicely.
