5 Best Hydration Bladders

All hydration bladders might seem the same but there are several things you should consider when choosing your next hydration bladder. First you'll want to consider the size of the bladder and be sure it'll fit in your pack. Next you'll want to consider how much water you'll actually need and consider the weight of that water. If you are going on a short hike chances are you don't need a 100 oz hydration reservoir but if you're going backcountry backpacking you'll likely want the biggest hydration bladder you can get your hands on. Below is our list of the best hydration bladders we carry, You can shop all hydration bladders here.

What Customers Are Saying

Easy to use and quality construction

I use this in my Alpz Outdoors Dark Timber day pack while scouting or hunting. I find it easy to fill, empty and clean. A little baking soda and water took the plastic taste right out. Keeps me from having to carry bottled water and having is slosh if not completely full or empty.

Typical of Eberlestock - Meaning Outstan

This component is on board as a part of a preparedness system. I do use it with an Eberlestock Terminator, it fits and dispenses perfectly. Good heavy duty materials and construction. I really like being able to open the entire end to allow for cleaning and full drainage and drying. I would buy it again, and would recommend it to anyone. If the mouthpiece didn't fit the loop, I would simply buy a clip, or use a tie-wrap to slip it in and out of. IMHO, both Eberelestock, and Midway, are unbeatable.

What Customers Are Saying

Excellent Replacement

Excellent replacement that went inside my 2002-issued Camelbak M.U.L.E. The only difference is the reservoir opening was not as large as the original. It's a tad more time-consuming to dump ice cubes into the normal-sized opening. The hose and hose insulator tube function nicely. The NBC (chemical mask) connector i no longer have use for so I tossed that piece. The water stayed cold for about 6 hours with the ice I put in there. I would recommend buying the plastic drying hanger and bristle brush designed for this bladder. The old Camelbak bladder with much larger reservoir opening was easier to clean. But, I am still satisfied with this product.
