Question: How do you carry this? My pack has no outside compartment to hold the hydration system. If I put it in the pack I don't see how I will access to it.
Document: This 3L Platypus worked wonderfully on an 800-mile walk of California's El Camino Real in May and June of 2013. Rather than carry it in the central hydration pouch of my Gregory Baltoro 75, which was occupied by an iPad, I placed the bladder in one of the side pockets of the pack, which could easily have accommodated another bladder on the opposite side (which probably would have been better balanced.)
With this bladder, I wash my hands of the Camebak brand and I fully embrace Platypus!This hydration bladder is the bomb. First of all, the GIANT zip top closure makes it easy to fill from a stream while fully eliminating leaks, event when put in my pack upside down for hours at a time.
I have not had a hydration pack at all recently, but a couple friends picked them up and they seemed to be pretty compellingly useful. I browsed online and in store to see what I liked, and pretty much based off reviews alone I chose this 3-litre one.Top: The zip close seemed a little bit peculiar and I wasn't overcome with confidence, but I've used the pack probably ~50 times and haven't had even the faintest issue with water leaking.
Great hydration system. My first outing with it was just a day hike so I loaded it up in my day pack. No leaks or spills. I'm looking forward to using it on a longer backpacking trip.
I bought this hydration system because I already had 3 backpacks and didn't want a fourth. It's worked out well and I love that I can take in water without having to stop and remove my pack.
I bought this not to use as a hydration system - I prefer (IMO) the Source brands used by the Military.Parts you will need:a.

The bladder fits well in my 28L day-pack. I would have got the 3.0L, however this would have been too large for my bag. The zip system to open the bag is easy to use and aids in cleaning. I've read many reviews that encourage people to roll the bladder up and store in a large freezer bag--in the FREEZER. This will prevent anything nasty from growing inside the bag/tube, which leads to the early demise of so many hydration bladders.
It's my second one. I use two of these to form a gravity feed filter system. It's a great product for a resonae price. Three liters is about the max I want to carry on my back at a time so I like the size. The hose detaches easily and does not leak at all. The bag is well made and seals nicely. It just works!
Its been a while since I last had a hydration bladder, the previous one being an early model of the Big zip that lasted almost 6 years.So far this has been solid, I like the quick disconnect, carry handle and the securing slider, they're certainly great improvements over the original.I haven't noticed any chemical taste, even though the water that's in there has been sitting for a while now. It has served my purposes great so far.
Purchase this to go with a Sawyer mini water filter after watching a YouTube video that someone produced showing how they set a similar system up this way. The wide mouth makes it so easy to fill. Put the Sawyer mini in line and off you go! Whether your a hiker or Prepper, this is a great bag, we'll made and worth every penny.Big jim
