Recent Hydration Reservoir Reviews

Platypus Big Zip LP

rated 5 of 5 stars I have the Big Zip 3 liter and I love it. BPA-free and easy opening. I used to have the 2L but recently got a 3L and I'm glad I did. I like how there is a divider in the bag so the water fills evenly. I also like how it is BPA free. I prefer the Big Zip over the Hoser because I can open the bag with ease to put more water in and to pour out. Full review

Source D|vide

rated 5 of 5 stars The Source D/Vide hydration reservoir redefines flexibility of purpose in a hydration reservoir. It performs without flaw, has excellent ergonomics and reliability in the bite-valve design, is highly resistant to additive taste from its construction materials, and it doesn't leak under heavy use (from anywhere). It is easy to clean and refill, and creates a brilliant, simplified solution for those of us who want to easily carry more than just water for long MTB rides, backpacking trips, snowshoe… Full review

Osprey Hydraulics Reservoir

rated 5 of 5 stars A great reservoir! And easy maintenance. Here is another great product by Osprey! This product comes in both 2L and 3L, mine of which being the 3L, and it is held well, and offers plenty of water for the backcountry. I've had a few reservoirs, and this one is my favorite to date.   It fits into multiple packs well, even at 3Ls.  Including a Talon 22, which is not the largest pack, but 3L is held just fine; as well as my Kid Carrier by a different brand (which I was a little leery of the fit, but… Full review

Sea to Summit Pack Tap

rated 2.5 of 5 stars This is a great product that served me well for two years of about once monthly use. I was loving the ease of use and the ability to carry so much more water. It was all going well till out on a hike the Pack Tap started leaking around the seam that the opening attached to the bag with. I can no longer use it as it leaks too rapidly. Luckily it broke on me on my last day of the hike and I had another bottle with me to use. Full review

Platypus Hoser

rated 4.5 of 5 stars Great reservoir, no taste or smell, and no leaks. I've been a hiker for a while now and have always used a simple Nalgene bottle, but finally gave in and purchased this 3L Platypus reservoir to go in a reservoir compatible day pack I already owned.   My first issue was that the sleeve in the day pack was too small for this enormous water bladder. Once I got it situated in my pack and routed the hose I was all set. The advantage of course is that when I want a drink I don't have to try and contort… Full review

MSR DromLite Bag

rated 4.5 of 5 stars Light and effective water supply bag for backpacking. I've used the 6L sized bag for many years. I carry it empty until near camp and then fill it as a water supply for around camp. These DromLite bags are a little lighter than the black MSR Dromedary bags. They are sufficiently durable for backpacking. I've never had any leakage issues, and the contents have never had a bad taste. I once had to replace a bag that was punctured by a pair of teeth from a pesky rodent wandering around camp at night… Full review

MSR Dromedary Bags

rated 5 of 5 stars I have borrowed the 10L dromedary from a friend a few times and love it! I have this dromedary on my list as one of my next purchases for sure. This dromedary stands up to a lot more than a plastic dromedary will. I have used it on a few treks and absolutely love it. It is very convenient that I am able to attach the dromedary to my backpack, instead of having to lug something by hand around to have water. Full review

Platypus Hoser

rated 5 of 5 stars Goal: hydration system that works all the time, is comparatively durable, works with multiple water filtrations systems and components, and is the lightest weight. Bar none, the solution is the Platypus Hoser. I am more of a hiker and less of a camper. So my hydration system needs to be more for an athletic backpack that takes a beating. In other words, I would be more forgiving if my hydration system was not perfect for camp. So, I was thrilled to discover through many miles and camps that the… Full review

Source Widepac

rated 4.5 of 5 stars Revolutionary design for a water bladder and it's just as tough as they say it is. Love the slide closure! Great for backpacking (3L) or hiking (1.5 or 2L). Keeps water fresh for days. Okay, I don't know where I read the first review for this bladder, but when I watched a car drive over a full one without it bursting, I thought "what the hell do I have to lose?" I'd never heard of SourceOutdoor and although I was tempted to go with a Platypus for about the same price, I decided to try the Widepac… Full review
