Platypus's Big Zip LP is their flagship hydration bladder and its packed with features, such as the large sliding clip that completely opens the top allowing you to clean the bladder inside easily. The bit valve has a locking mechanism which stops it spurting water when you accidentally sit on it, the tube can be disconnected at the bladder outlet so you don't have to re-thread the tube everytime you need to refill.
They seem to have thought of everything - LP stands for Low Profile, which means they have fitted an internal wall to hold the back and front of the bladder together - thus stopping it from becoming a tube shape.
Bladders are really good if you're not good at stopping to take a drink as they are so convenient you take lots of short mouthfulls as you go which eliminates the risk of dehydration. They aren't so good if you want to use them around camp because they don't have a proper opening, The Playpus Hoser is the alternative, less convenient in use on the trail, but the bladder takes a standard cap so you can use it as your camp water container.
