Description

Easy to remove, clean, and use.

A quick-disconnect fit on the end of the Platypus Big Zip SL Hydration Bladder's drink tube means you can easily remove the water reservoir from your pack without re-routing the drink tube, while the SlideLock closure prevents the wrist-tweaking that usually accompanies threaded closures. Platypus made this bladder with BPA-free material and added a SlimeGuard antimicrobial treatment to the inside. An angled shutoff valve helps prevent leaking after you take a swig.

GOAT IS GOOD

Got a couple nasty/rank camelback bladders that I didn?t care for properly and needed replacing. I have a geigerrig that is in good shape but I wanted a bigger bladder for a recent desert bikepack trip where I needed to carry a couple days worth of water before we could resupply. So I supplemented the 4L reservoir from the Platy Gravity filter I had with this 3L bladder. Holds water?can reach in easily to clean it out if needed (or wedge something in there to help it dry). Its lightweight for transporting when empty (lets face it, water is about the heaviest thing you?re going to carry when doing anything in the backcountry). Something of note for very specific needs---oversizing the bladder with a little less than its capacity in water lets you bend/fold/shape the bladder into some funky places. At different times over three days, the 3L and 4L both spent some time in my bike frame bag conforming to the triangle shape and around bike tubes and tools and a stove? Kept the excess water weight off my back, helped lower the center of gravity and held up (no leaks or punctures) even with all off road mileage including bouncing up and down some big elevation changes at speed.

Doesn't leak! Very good quality and easy to fill up.

Can anyone comment on the flow from the valves between the Platypus and Deuter bladders? I have the UltraSpire bladder, which has great flow, but doesn't maintain pressure, so each time you want to drink you have to suck all the air out first. Terrible design, especially for runners.

Best Answer Responded on

The flow is great and it's easy to suck water. I don't recall having to suck any air at all. I've never used the Deuter bladder.

may I ask what is the advantage of this type of system over a normal water bottle or canteen??just curious..I mean water in your pack equals wet gear and clothing does it not??Im not new to packing,just to all these new gadgets...

Best Answer Responded on

A few advantages:

-- lighter weight to hold a larger volume of water

-- The flat nature of the bladder is easier to pack and, when empty, takes up almost no volume in a pack (unlike a bottle)

-- most packs hold these bladders at the ideal location for heavy gear (mid/high, centered, close to the back)

-- the tube makes it easier to hydrate while moving. ("handsfree")

-- The larger volume makes it easier when filtering/purifying water

-- I like to hang mine up on a tree in camp, at which point it becomes a gravity-fed "faucet" for anything I need.

All that said, I usually carry a bladder AND a 16oz insulated bottle. That gives me the versatility I like for drinking like a normal human, hot liquids, sharing, and my bottle serves as a tiny bear canister to store a midnight snack.

Responded on

I just want to add that most packs these days have a hydration sleeve to keep your bladder separate from the rest of your gear and the only way your gear is going to get wet is if you puncture the bladder which has never happened to me or anybody that I know personally.

Responded on

David and Wayne highlight great points. Weight is key, and this system is pretty light, even for a bladder. I personally own this system, and it does NOT leak (if used properly, of course). It even has a disconnect between the hose and bladder that allow you to remove/attach a full bladder with little (<1 tsp) to no water loss. I fully trust this bladder to keep everything dry.

It is GREAT! Just BUY IT!

  • Familiarity: I've put it through the wringer

Well made, and very heavy duty! Cascade Designs has the most liberal lifetime warranty ever! (Yes, I had to send it in after it got a pin prick in it, was "field repaired with a hot knife and a piece cut from the top corner material. They sent me a new one-no questions asked.) The large opening is great and I LOVE the detachable hose, because it has a valved connection so you can leave it off with it full. (The non-Zip model is cheaper but doesn't have this.) Very versatile. Just plain good stuff!

I wouldn't use anything else.

  • Familiarity: I've put it through the wringer

I've used a few different reservoirs in the past and this is by far my favorite. The big opening makes it really easy to clean out when you need to. The bite valve is sturdy and drip free. I love the quick disconnect hose, it makes it super easy to get in and out of my packs without messing with the hose. The quick disconnect parts are also compatible with my Katadyn Hiker Pro filter. I have had mine for about 3 years and it is still going strong.

Reliable and a Must-Have!

  • Familiarity: I've put it through the wringer

Have had the Bladder for the last year and have used it, on average, 1-2X per Week. I have the 3L Bladder and find that it's the perfect size for longer day-hikes and overnights. Super sleek-profile. Solid hose to bag attachment. Mouthpiece has never given me problems - even has a lock so it doesn't leak while you're on the move. I bought this one in particular because of how easy it was to clean - which is super important for an an investment such as this one. I just bought the insulation for it - can't wait to use it this winter without it freezing up!

Solid

  • Familiarity: I've put it through the wringer

I've been using the same one for a couple of years now in hot and cold conditions with no issues. I previously used the Camelbak Antidote and went through several due to leaks before realizing that it just wasn't going to work. A friend suggested the Platypus so I got one and never looked back. Even under the pressure of a fully loaded 70L pack, never a drop out of place. It's super easy to fill and clean and the mouthpiece is much more user friendly than the CamelBak (more water volume, more durable, and more comfortable). Stop reading and get one already!

Not my favorite

  • Familiarity: I've put it through the wringer

This bladder let me down. It has some cool features. The big zip on top is awesome and makes it easy to fill. But I bought 2 of these bladders and they both started leaking out of the hose connection at the bottom of the bladder. Halfway through my hikes my whole pack and back would be soaked and I would be out .5 a liter.

Responded on

That's a bummer. This happened to me only once, a few weeks ago. It seems to be an isolated incident...Probably user-error on my part though. Set it up real early in the AM, before the coffee..

The BEST bladder

  • Familiarity: I've put it through the wringer

The Platypus Big Zip's top makes this the easiest to clean bladder on the market. When it starts to get funky (which it really hasn't up to this point, and not because I have taken good care of it), you can just scrub it out with one of those dishwashing sponges with a handle, and it becomes as good as new again.

Convenient

  • Familiarity: I've put it through the wringer

These hold up better and take less abuse than the hand held 1Ls.
Filling up and using tablets is clutch. Not easy with a hand pump, best to use with gravity filtration system.

I like more than my CamelBak stuff

  • Familiarity: I've put it through the wringer

I really like the clear bag. It is durable and easy to clean. My Platy products seem to taste better than my CamelBak bladders - plastic taste. I find the Big Zip easier to fill and clean than my CamelBak stuff. The quick disconnect makes removing the bladder easy.

I originally had concerns of water leaking from the zippered top or the quick disconnect; but, I have had no issues with either and am confident in the durability of the Big Zip SL.

Great product. More spendy than the basic bladders; but, worth the money due to features, ease of use and cleaning. I love the Big Zip, have no issues and highly recommend it to others.

Is the material the bladder is made of resistant towards boiling water, or will it change size due to temperature?

Responded on

I have never put boiling water in my own platypus, but the people in the thread below seem to say they have had no detrimental effects from putting boiling water in theirs. sounds like you should be set to go.

Responded on

Hey Steve, we didn't carry that Click Elite Pack, so I checked around online. I'm not sure exactly which model you have. If it was the Express model with the computer sleeve for 15" Laptop or iPad, you will have ample room for any of the 3 sized Platypus bladders.

The description of this bladder says "A quick-disconnect fit on the end of the Platypus Big Zip SL Hydration Bladder's drink tube means you can easily remove the water reservoir from your pack without re-routing the drink tube"... so does that mean I *don't* need to purchase the quick-disconnect kit ( http://www.backcountry.com/platypus-quick-disconnect-kit?ti=UExQIENhdDpIeWRyYXRpb246MDo2 ) in order to tidily disconnect the hose from the pack? ie... it's already set up as is?

Best Answer Responded on

Correct. No need to by the quick disconnect seperado. The disconnect that is sold separately is to modify other hydration bladders to have a disconnect valve at the base of the bladder. But this bladder already has one.

Quality is Great

  • Familiarity: I've put it through the wringer

The best thing about this bladder is the quality that platypus put into it. I have the 3.0L and use it as my bladder whenever I need one, even when it a bit big it folds over nice! I also really like the bite valve as in it does not break as I hear a lot of other bite valves doing. I have noticed that as in all bladder hoses, if pinched in bag it will stop flow but great bladder and has done me well!

Nice one

  • Familiarity: I've used it several times

Nice piece. Like Source's/Camelbak's bite better, but the rest of the package is better here. This do probably not leak as quickly as the Source (regular bite) (?time will show?). Like especially that the container is clear / transparent. It is easier to clean this way. The quick release and open/close is very good.

Excellent

  • Familiarity: I've put it through the wringer

This will be my second platypus bigzip i have the insulator system as well these things are great no problems here just quality gear. I love the large mouth which works great to add water at the sink or in the backcountry. just got my girlfriend one and I'm sure she'll love it and she can stop using mine when we hike together. Much better than any camelbak I've used, no plastic taste. This and a nalgene and you're set for a while.

Great bladder

Pros
------
- No leaking.
- Easy to clean.
- Easy to seal.
- If the tube freezes then you can disconnect the whole tube and tuck in your jacket to defrost. This is possible because there is a valve where the tube connects to the bladder. Great for winter usage.

Cons
------
- When used with my Camelbak Mule pack, the tube seems too easily pinched. When I pull the tube up to drink it pinches. Need to unclip the tube, drink and reclip. Maybe just how I have the tube routed.

Overall, I'd buy this bladder over the Camelbak alternative.
