Platypus Big Zip SL Hydration Bladder

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.

Bottom Line: Easy to remove, clean, and use.

Platypus Big Zip SL has lots of features.

By: Merebea Danforth
September 16, 2008

I recently got the Platypus Big Zip SL bladder in the 2.0 liter size to put in Patagonia's 750 cu Endurance Pack, primarily for mountain biking. I thought that the basically glorified zip lock bag design would be good for easy filling and drying out. (I always like to get my hydration bladders as dry as possible so strange things don't start growing...) I also liked that this bladder comes with a shutoff valve and 90 degree bend for the mouthpiece, unlike with CamelBak which sells the bladders and shut off valves separately unless you buy their whole backpack. The piece that makes the drink tube removable does add a bit of bulk, but with a bulkier mouthpiece and shut off valve, it is nice to be able to route the tube in the other direction and just leave it there. It also gives the added bonus of helping the tube dry out more quickly when it is detached. For now I'm pleased, though I'm wary of so many "extra" parts that could break. All the more reason to get this through Backcountry because of their sweet return policy. I guess only time will tell. I know people who prefer the Platypus mouthpiece to CamelBak's, but for me it's taking a bit of time to get used to. Overall, I think it's a neat design, and if you're looking for an alternative to CamelBak's bladders, I would definitely recommend you give this one a try.

What does BPA-free mean?

Flag

BPA stands for Bisphenol A, a chemical compound commonly found in plastic drink and food containers. Small amounts of BPA may leach from containers and be ingested. Naturally, there is much scientific debate regarding what levels are harmful to humans. For further discussion on BPA, check out http://www.thegreenguide.com/doc/114/bpa and http://www.cdc.gov/exposurereport/pdf/factsheet_bisphenol.pdf.
***********
EDIT: BPA may cause cancer if you consume it. However, I have heard that the only way to get the BPA to leach out is to drink boiling water out of the bottle. But check the facts.

I wonder what's worse, consuming BPA or drinking boiling water?!?
