Collapsible by nature, they pack flat for efficient packing and our Big Zip™ opening makes filling and cleaning a breeze. The biggest, 6L tank weighs a mere 4.4 oz (124g), making it just as practical for group backpacks and river trips as it is for summers on the road. New features include our new, more durable film, a lower, more stable design and reinforced handles for easy carrying.

All of the other "better priced" (lower priced) drinking tubes and reservoirs I've used eventually just started not working or became too difficult to drink from. This Platypus tube is rubber(or something like that) so it's very soft and flexible. When you bite the end to take a drink it actually opens wide and you don't have to suck on it so hard.
Here's the deal with these on-the-go water reservoirs and their accessories: when you begin to use them they will ALWAYS have some kind of factory taste for the first few uses. My experience with the Platypus brand is that you don't have to rinse it a million times to get the taste out. Here's what you do for the best and fastest results when getting rid of the bad taste: fill it with water and let it sit for a few hours. Then empty it and rinse it a little. Fill it with water again and leave it for a couple days. Keep filling and emptying it every couple days until the taste is gone. It shouldn't take more than 3 times to get the majority of that bad taste out. Same goes for the drinking tube as well, I usually leave it attached so as to do it all at once. Every time you empty it, squirt out some from the drinking tube for about 30 seconds. My family has still been using their old reservoirs for a year-ish and they still taste bad. I've had my new Platypus one for a couple weeks and already absolutely love it.
So, no way around the fact the zip does not want to stay closed when the unit is full. The slightest outwards pressure on the carry handles causes the zipper to pop open. But this issue is fairly easily remedied.
When I first received it, I used some paracord type material run thru the handle grommets with one knot and the use of a cordloc to secure the center of the zip. This works pretty well and may be satisfactory for most people, particularly if you aren't trying to pack it while full in a backpack. If you really want to make it secure, go to the hardware store and get two sets of 1/4 inch aluminum screw posts. These fit the grommet holes perfectly and you almost certainly will not get the unit open without first removing the screw posts. Bit of a pain, but not too bad and basically bomber then.
Definitely loses a star because I had to engineer a fix myself. For its cost, this thing should have come with some way to securely close it. It works for my purposes, however, and I will keep it, but I probably would rate it 3.5 stars due to expense and design issue. There probably are cheaper alternatives for many users. The waterbrick is an interesting concept (I have one) and, if space is not a constraint, you might want to look at it.
After buying this, I also bought the SE - Emergency Water Bag - 5 Liter Capacity, 180 Micron - EWB5L for less than $5 on Amazon. It's 3 days after I filled it up with water to check for leaks and its still not completely dry inside (mostly dry but can still see water droplets). So, the Platypus design makes a huge difference to drying time. This one also feels more "brittle" than the Platypus and the handle clearly will not last as long. To be fair, it is touted for "emergency" use where the Platypus clearly is designed for real world regular use. The SE water bag may well work for many people who aren't going to be overly rough or accessing difficult water sources. I just wish the Platypus was a bit cheaper and they should have included something to secure closure at the price charged.
Just got back from a 7 day trip. We were filling our water bags from the fresh water output at a cattle tank. The first time I filled, I put this bag in my pack. By the time I got back to camp, half the water had leaked out. Even with the fix I noted in place, the water pressure still forced the zip open between the handles. At the second fill up, the handles had to be interlaced to create cross tension and we had to hand carry this bag--a real PITA in the terrain we were in. That at least stopped the leak which occurred between my added screws. My buddy was using an MSR bladder and we had zero issues with it. I packed it in my pack and put serious pressure on it with my tension straps with no issues. I'll be switching to the MSR. Unless you just want to buy something that really doesn't work for its intended purpose, I would look for other options. Barely functional if your going to fill it in your kitchen sink and put it on the counter.
