Our backpacks are ready to accommodate our top-of-the-line hydration systems. You'll find that they have dedicated bladder pockets, louvered tube portals, and tube-friendly harnesses. We think this is the ultimate hydration bladder system. Made by Source®, our premium bladders are BPA-free, uses patented anti-bacterial technology, and Glass-Like™ liner, so that you get a product that gives great tasting drinks and long life. We've added our own specifications to make this into the hydration system that best fits our products and the things that our customers will be doing with them. Special standard features include a weave covered insulated drink tube, a lockable bike-bottle style push-pull drink valve with a dirt shield. Dual-fill options allow open-end access or use of a screw-off Nalgene size cap.

Please note: This bladder is recommended for all Eberlestock packs, with the following exceptions and caveats: It does not fit the X1 series packs. It fits in the main outboard pockets of the Phantom and Halftrack, but not in the narrow sleeve with the hydration hooks.

100 oz. / 3 Liter Hydration System

Hydration bladder for back pack

Well made and very robust. Works well and I expect it to last a long time.

Wilderness elk hunt.

I just returned from a wilderness elk hunt. It certainly served the purpose for what it is supposed to do, however, there is a plastic taste to the water and when filled with 3 liters it dosen't fit easily into the Eberlestock pack for which it is supposed to be designed to fit.

Excellent arrived sooner than expected

Will do business with this company again soon.

3l hydration system

Good product. Leak free and easy to fill and also open up fully to clean and dry. I like the protective cover on the drinking tube as well. Tube could be just a tad bit longer but works fine in my Team Elk pack.
