Great Water container
This water reservoir & accompanying tube has the features I was looking for, over Camelbak (which I also have used in the past).
1. The handle allows you to carry water back to a campsite (to use, or filter/ purify) without the tube attached.
2. There is a quick release place at the bottom of the reservoir that the drinking tube plugs into. However, you don"t have to keep the tube in permanently, & just unclip it, to use the reservoir stand alone as a water container.
3. When carrying this container in your pack (without the tube), the wide opening allows easy pouring into any container (unlike Camelbak. This issue was important for me as I need to fill my dog's water bowl on trail).
4. I have a Kelty Trekker external frame backpack. Its area for holding water bladders is horizontal. No problem, I was able to drink water easily from the drinking tube, when this Platypus Big Zip is positioned sideways in the pack.
5. It fits into the REI day pack/ stuff sack called the Flash 18 (I use the Flash to stuff my clothes in while backpacking, then use it for hikes from basecamp).
6. The Platypus didn't leak ever on me on several backpacking trips.
7. The drinking tube for the Platypus Big Zip, also has a twist lock on it, to prevent leaks.
When I backpack, everything needs to have 2 or more uses (otherwise its excess baggage/ weight). This is a water container, water carrier, plus a hydration system.
I am very happy with this (& when I bought mine, my spouse had to go get the same thing the next day, lol! :)
My old hydro pack developed mold so I needed a replacement before my Mt. Whitney hike this year. I picked this bag due to its wide opening up top. The wide opening makes it easy to transfer water from my nalgene bottle into the Big Zip. The wide opening also makes it easy to clean and air dry with my wife's egg beating utensil. The only thing I didn't particularly like was having to bite the bite-valve just right to get the water to flow out. It wasn't a big deal, but when you're tired, it can be a bit annoying when you just want a drink. The on-off feature prevents drips, but requires two hands to undo so it is also another small step you must do when you're tired. The clip is a nice feature to keep the tube from swinging wildly and keeps it near your mouth for easy access. The product appears to be well-made and it looks like it will serve me well for many years to come. I would recommend it to all backpackers, but if you're cycling, I wouldn't recommend it because of the on-off switch that must be manipulated.
Really glad I bought this. The big zip makes it easy to pour in water and clean, as long with dry. the product is also very durable plastic. I really like the feature of the removable drink hose. It makes it easy to refill without taking the whole hose out of my pack when refilling.
I have hooked up a sawyer inline filter to the hose, which works great and never have any problems. The nice part too is that it is clear, so I can see if debris is floating around in it when I put in dirty water, which would then clog my filter. The big zip makes it easy to reach a hand in if necessary.
The shut off valve is very convenient and was only necessary after several months of high use. I am not a fan of Camelbak products, and this was the right choice for me.
Great buy, no drip, easy refill
Was very pleased with this product. I needed a hydration bladder for my pack and didn't want the "flavored" water you get with the camel bak. This is the perfect product the big zip makes it super easy to fill and does not leak. The detachable hose which for me was a luxury at first has become a must have not needing to take the hose out with it cuts refilling time in half. No funny taste at all and no problem with mold growth either. Love the locking bite valve and love the flow of this so smooth. Easy to clean just unzip wash out and use the blue "zipper" to hold the bag open while drying. All around a great buy
Does the job
This is my first reservoir and I am quite happy with my purchase. Taste is clean, pouch is easy to fill and clean, and 100oz lets me fill it up for those hot, dry hikes. Sucking water out of a hose takes some getting used to. I wish there was a way to turn it "on" and have the water flow out without having to "suck". Issue should be easy to fix as next time I will take the reservoir and a small bottle for those really thirsty moments (lunchtime), when I need to rinse something or just pour some water on my head.
I've been through several water reservoirs the past few years and haven't come across a decent, reliable one with the features I wanted. Finally found the Big Zip and couldn't be happier! If you're questioning the zip closure, there's no need to worry, even without the "Zipper" on, this thing will hold liquid in all directions. Works PERFECTLY using the supplied adapter of my Katadyn Hiker filter; detach the drink tube, snap the filter hose in, and pump away, no need to re-route the hose as it detaches from the bladder.
Easy to clean, easy to use, worry free... Excellent product!
Excellent hydration pack
I love my platypus! The wide mouth makes it easy to refill, easy to clean, and easy to dry. I had no problems with any of the connections, leakage, or the easy to use mouth piece. The water tasted fresh when I used it and only developed a plastic taste when I mistakenly left water in there for 3 days. I also like the little clip attached to the hose so that I could clip the hose down and not have it swinging around while hiking.
I had a hard time deciding between Platypus and Camelbak. I went with Platypus because it was cheaper then a similar sized Camelbak bladder. This is a great bladder; the huge opening is easy to fill/add ice, the quick release on the tube is very handy, and the addition of a shut-off valve into the tube is wonderful.
The construction of the bladder seems to be top quality. And no plastic taste at all.
This hydration reservoir... it's simply amazing. It literally takes less then 5 seconds and EVERY single drop in the bladder is out. You can CLEAN and DRY this bladder in less then 2 minutes. No more nonsense with curved brushes, pricey tablets, etc. This is simply the best reservoir created. Osprey doesn't even come close with their 'revolutionary' framed and state of the art reservoir. This reservoir is amazing!!!!!
Really good water reservoir!
I got this water bladder because it was one of the only water bladders that could fit in my REI Jet UL pack. So far, I have loved it! It doesn't leak at all, filling it is a cinch, the quick release valve on the bladder is very handy and doesn't leak, and the shut off valve on the bite valve works very well.
