Confused
Purchased a 3L and loved it…..until the bite valve came off and we found that the bite valve & shut off valve were filled with some sort of gel-like substance. Can’t even remotely clean it out. Searched for info on what it is, and can’t figure out what it is. SO disappointed.

Big Zip 3 liter Bladder
This is my 2nd one. Finished the AT with my first one in 2012. Still working but time for a clean bladder. Backpacked with it this summer and still love it as much as I did on the AT!

Some great features but one major design flaw
No plastic water taste, great flow and awesome improvement on the bite valve BUT water stays in the fixed hose on the back after you’re done using it and it’s a pain to get the water out so it doesn’t get too funky. The old version had the hose valve at the bottom which never allowed water to sit unless you left the hose on. I wish you guys made the old version with the new bite valve, that would be the magic recipe.

Great design and durability
Flow is great, ease of filling is awesome, like the water tube attachment and fits well in my pack.

Universal attachments, wide opening.
Serves its purpose. I like the big zip for the wide top opening. Flow is fine if hose doesn’t get kinked even with MSR thrulink attached. 4 stars as it could be lighter and is on the heavier side of bladders if you are concerned about every ounce of weight. I would still choose this option over the Hoser bladder as these connections are all universal attachments for other brands.

Non sealing
I have used various Platypus units since they first hit the market. I got a 2L Evo as my Big Zip SL developed a small hole at the bottom. I put this in my bag and into the boot of the car. Ninety minutes later most of the water was in my rucksack or the car. The top seal is hopeless even with the poorly fitting blue “handle”. Water pours out. Useless. What have you done Platypus?

Easy to use
I’ve only had a chance to use it once so far but enjoyed the fast water flow and how easy it was to fill up. Seems much sturdier than it’s previous

Good and yet...
Pro: Good flow, good capacity. Didn't leak. Bite valve works great. Con: I found that the handle (blue ) pulled away from the reservoir (clear) when inside the pack (Deuter Speed Lite 30) and full. This happened if the handle was attached to the pack's reservoir holder (velcro support/hang tab) that keeps it in place. Doesn't happen if the reservoir is only partially (about little over half) full. Did not leak though.

Just OK
Just OK. Would be better with a stiffener to aid in stuffing it into the pack. Lacks a magnetic clip for the drink valve.
