Platypus Big Zip SL Hydration Bladder

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.

Putting ice in the platypus bladder is easy and I like the bite valve a little better over the Camelbak's.
