I really love this one

Rating:*****
I have used many hydration bladders. I'd settled on Platypus 3L Hosers with a quick release valve add-on for the best high capacity no leak reliability.

This blows those away.

The zip top allows for easy fill (incl. big ice blocks), cleaning, drying & carrying/hanging and is now secured to resist pack compression (previous worry with Big Zip).

The bladder easily mounts into all my packs - expedition/weekend/day/hydration only - it has good top attach options, the right dimensions & nicely rounded corners.

The quick release fittings are standard size (match Camelbak etc)and are molded smoothly to the bladder side. The bladder valve seals when disconneceted so you can carry a full extra bladder for a quick swap.

The bladder has easy to read fill lines (the "right way" up!).

The hose is a standard Platy type with their bite valve which I consider the industry's best for flow/no leak (and now they finally added an optional bite valve cover too!).

Its not the lightest option - though the plastic zip lock bar could be removed. The materials (like the new hosers) seems to be very strong/reliable (repairable even) more flexible than the old style hosers and imparts no taste issues at all.

...I'll just give away all my hosers and buy 2 more of these. For me this is perfection!

Great bladder

Rating:*****
This product works great with both my backpack (Deuter Air Contact 65+10) and also with the Katadyn Pro filter.

The Platypus allows you to disconnect the hose to pull the bladder out of your pack and hook directly up to the Katadyn filter. The handle makes it the only bladder that easily fits the Deuter packs as well.

The plastic zip works great as a handle as well as for hanging it up anywhere. The large mouth is great for getting ice in for those extra hot days.

Better than camelbak

Rating:****
Love the easy to fill top. Can fill it with ice straight from the ice maker on the fridge with ease. I also like how you can easily unhook the hose with the quick connection. That way the hose can be left weaved through your backpack while the reservoir is refilled and hooked back in when you are done. The on/off valve could be easier to use but it works just fine. Years with a camelbak but this is at least as good. No plastic taste either.

Great hydration bladder

Rating:*****
I just returned from a 10 day backpacking trek at Philmont Scout Ranch in NM. The Platypus worked great on the trails and was easy to remove from by Deuter Air Contact (65+10) backpack. The detachable hose at the bottom of the bladder made removal and refilling of the bladder easy.

Negative Reviews:

Deceptive - 6 ounces not 4.5

Rating:**
If you are an ultralight backpacker the Platypus Big Zip SL 3 Liter Hydration System is deceptive. They claim that the hydrator is 4.5 ounces period, but when I received the system it was 6 ounces. I called Platypus and they said you have to take the top part off to get the 4.5 ounces. Take the top part off! Why don’t they say this! It would not have been worth the change from my Camelback. It seems like a great system, but ultralight backpackers be forewarned!
