Recent Hydration Reservoir Reviews

Hydrapak Shape-Shift 2L

rated 4.5 of 5 stars A unique folding opening makes filling easy and is leak proof. Shape-Shifts baffle gives the reservoir a slim shape. Plug-n-Play hose disconnects without removing from your pack. As someone who has been using water reservoirs for over 25 years, it was exciting when I got a chance to test Hydrapak's Shape-Shift 2 liter reservoir. My pet peeves through the years have always included leaky threaded closures, a bulbous profile, cleaning issues, and bite valves that to often leaked onto my shirt. The… Full review

Gregory 3D Hydro 3L Reservoir

rated 2 of 5 stars A reservoir with innovations that make sense, but durability could be a big issue. The main advantage is the three-dimensional shape of the reservoir, which allows it to easily fill and dry out. Other plus factors include a fold-away hook to hang it up, an easy-to-use open/shut valve, a sturdy hang hook (if you use it with a Gregory pack), and a baffle to prevent water from sloshing. With or without a Gregory pack, this reservoir should have been a worthy competitor for your hydration needs. Unfortunately,… Full review

Source Widepac Hydration System

rated 3.5 of 5 stars The Source Widepac 2L Hydration System is a functional and fully-featured hydration system. The product promises a virtually maintenance-free system, negating many of the common hygiene issues associated with water reservoirs. In this regard, the Widepac does not disappoint. Despite heavy use and abuse, I did not experience any problems with microbial growth. Most components of the system also combined to provide taste-free, clean water. The Sawyer Mini Filter, as part of the Source Water Filtering… Full review

Cenote Hydration System

rated 5 of 5 stars Lightweight, recyclable water bladder. This hydration bladder system is much lighter than other brands. If you hoist some of the other companies products you can see why many people opt not to use them. I have had this for two years of biking, hiking, and kayaking and it is still going strong with no signs of wear or fatigue. Over the years I have had bad experiences with other bags getting gross from the use of anything other than just water. I trained myself to stay away from any mixes or sport… Full review

Platypus Hoser

rated 5 of 5 stars Bulletproof and lightweight way to keep hydrated on the go. I've had a 3L Hoser for about 3 years now. I'll start with the one drawback: It's tough to get much water in it from a non-flowing source of water, but this is easily solved by pouring water into it with some other container.  Filling it from a flowing stream is cake. Besides that, I have nothing but praise for it. Even the one drawback actually comes with two big positives:      1. The opening is small, but that means you don't have… Full review

MSR Hydromedary

rated 5 of 5 stars I have the 3 liter variant of this bladder and it has been fantastic. It is well built and has taken a beating on the trails and quickly connects to my Miniworks filter so I can quickly fill it with clean water. This product is best for backpacking, hiking, camping, or really any outdoor activity. I even took mine to the beach one day! Some complain about the two loops as opposed to one, but my pack has two hooks for hydration bladders so it works great for me, definitely recommend. I bought this… Full review

Source Widepac Hydration System

rated 5 of 5 stars Practical and easy to use water bladder. Source Widepac 3L in a Berghaus Wilderness rucksack I picked this model of water bladder over others for two main reasons. It is a little lighter in weight. It opens from the top, which I find more practical especially when I need to pour water from the bladder into a pot for cooking. And its bite valve comes with a cover to keep dirt off the valve—a useful feature when you set your pack down on the ground and it topples over as packs do. The slider looks… Full review

Source Widepac Hydration System

rated 4 of 5 stars So much easier to open, close, and clean than bladders with screw tops. The new Helix bite valve is easier to clean than the original style, but too large and difficult to open/operate, especially one-handed (while biking). Overall, though, my favorite bladder. After years of struggling with the impossible to open CamelBak bladders, I was happily introduced to the Source slide top bladder. It is so easy to open and close that I was skeptical as to how leak-proof it would be, but I've never had an… Full review

Source WXP LP

rated 4 of 5 stars Holds water and no funny taste after a few days. This is also a very durable piece of equipment. I changed the bite valve since the original one leaked. This bladder is a great piece of equipment that is well thought out and does what it says it will. I had an issue with the bite valve so swapped it for a Camelbak—one problem solved. I have used this bladder for a couple of years and it is still in good shape, holds no funny tastes and doesn't leak. I would recommend it to anyone. I have the 3… Full review
