Backpacking Background: Car camped as a kid and did a little canoe/kayak camping as I got older, but never any backpacking.  Recently I took 2 trips that re-whetted my appetite for backpacking and now I am trying to take as many trips as possible though my heavy pack weight is often inhibitive. As a result, I am trimming the excesses from my pack and cutting down the weight on the essentials.  I am up to about 8 backpacking trips total, always looking for more.

Review:
Note: I bought the Platypus Big Zip as part of a hydration system.  As a result, this will review both the Platypus Big Zip and their hydration system.

I originally purchased the Platypus Big Zip because I drink a lot.  I am thirsty all the time, whether I am hiking or not, but especially when I am hiking (I used this walking around to classes and would drink about 200 fl oz (6 L) of water on any given day). I purchased the Platypus brand over others because it has a lifetime warranty (which I have used before on other Platypus brand water containers). I chose the Platypus Big Zip because of the ease of filling it with ice or powdered Gatorade. So far I have taken it on ski trips in the Rockies, hikes in the Appalachians, and kayaking all around the Southeast (including some sea kayaking).

Description:
This is a fairly standard hydration system with a 3 liter (100 fl oz) Platypus Big Zip reservoir.  It has a standard hydration hose and bite valve. It is made of some sort of plastic laminate (the same as all other Platypus products), but this has an extremely heavy duty zipper on the top of the reservoir. It is also lined with a food-grade polyethylene so that it will not flavor water with the taste of plastic. On the hose there is a small black clip that is intended to allow me to connect it to my pack or jacket to make the hose easily accessible while hiking. In addition to the hydration hose, I also got a standard cap so that it can be used just like any other Platypus reservoir.

Use:
I have used the Platypus Big Zip in combination with multiple packs, all with pretty good success. I used it with a hydration pack made by Source on a few bike rides around town.  This particular pack has a dedicated hydration sleeve designed to hold 100 fl oz, 3L.  I have also used it with my backpack around campus (I just drop it in there since it does not have a designated hydration sleeve).  In addition, I have used it in a couple of different packs when hiking (mainly the GoLite Jam, which has a designated 100 fl oz [3 L] sleeve). It has worked well with all of these setups and has never leaked. I also took it on a skiing trip in Utah with the same hydration pack mentioned earlier. It worked well there, but the hydration tubing froze solid at one point (it was well below freezing, about 18 F, -8 C). After that, I remembered to drain water from the tube by blowing air back into the bladder and never had another problem.

The bite valve works well, I bite and it provides water. The only problem is that it does not always stay on that well, and I have bitten it off by accident more than once. Maybe a screw-on valve of some type would work better. I would also like a little more volume to be provided when I bite down (see note at the top about drinking a lot). The little black clip that is supposed to hold the tube so I can drink from it is useless. I do not know what can be done to improve it, but there has to be something because it serves no purpose other than making it harder to thread through the elastic tube-holders on my pack's straps.


Durability:
The Platypus Big Zip has held up wonderfully. I have dropped it into the water by accident and it took a nice little trip down the Five Falls of the Chattooga River (class IV-V, very dangerous), I have frozen it a few times (both on purpose and accident), boiled it a couple of times, and sat/stepped on it more times than I can remember.  It is still going strong. Needless to say it gets thumbs-up on durability from me. One concern I had was the zipper: it allows me to put ice or powdered Gatorade in easily, but is a zipper, and anyone who uses Zip-Loc bags knows how finicky they can be. Once I started using it, though, it was very easy to close the zipper and it stayed shut very well. I had a couple of accidental spills to start with, but that was user error. As long as I make sure the zipper is shut, it has not come open yet.  Also, I believe the zipper will make it much easier to reach in and scrub if necessary, should scum build up inside, but so far I have not utilized it in this fashion. I clean it on a regular basis with a little bit of bleach).

 

 
Summary:
Good:
Durable
Freezable/Boilable
Zipper does not leak
Able to add powdered drinks easily
Easy Cleaning

Bad:
Bite Valve is sometimes bitten off
Black clip is useless
