The lightweight, flexible Platypus Big Zip LP hydration system is totally taste-free, BPA-free and comes complete with a drinking tube and HyperFlow bite valve. Tough enough to stand up to freezing and boiling temperatures, it makes an ideal upgrade or replacement component for an existing hydration pack, and instantly converts any standard pack into a hands-free hydration system. With a low-profile design, the Big Zip LP rides flat in your pack.
The Platypus Big Zip LP reservoir features a wide opening for easy filling and cleaning. The face-mounted hose port makes it simple to get the reservoir in and out of your pack. The ergonomic 90-degree shutoff valve allows for easy drinking and the HyperFlow bite valve delivers a high flow rate, which is important when you want to stay well hydrated while on the go.
The entire system is leak-proof. The Big Zip LP has an integrated SlideLock closure that ensures a secure and easy closure. Backed by a lifetime warranty, the durable tri-layer laminate film is extremely puncture and abrasion resistant. The reservoir and the drinking tube of the Big Zip LP feature Platypus's SlimeGuard anti-microbial treatment to ensure a completely fresh and taste-free system.
A quick connect fitting is included that allows you to use a water filter (sold separately) and pump filtered water directly into the Big Zip LP reservoir through the drinking tube.
The Platypus Big Zip LP hydration system is available in 1.5L (60 z), 2.0L (70 oz) and 3.0L (100 oz) size options.

Large opening, easy to clean
No weird smells or taste
Size is great for hiking/camping
- It stays flat and not bulk up in your backpack. The slidelock closure is easy to use and secure. It is easier to clean with the wide opening.

Dislikes: no malfunctions up to date to dislike
- Awesome bladder for backpackers
Likes: I love the huge opening in the top. It really makes cleaning and filling this bladder very easy. It's basically like an extremely strong zip lock baggy with a clip on top to ensure it doesn't open unexpectedly (and as a handle). The bite valve and quick disconnect is excellent.
- Nice hydration bladder. Can't exactly fit your hand in there but still easier to clean than others. Quick disconnect/connect is cool and makes things a lot easier and adaptable. Having a slender wide profile it sits against your back really flat and isn't
Likes: Pretty much everything
Dislikes: Bite valve, which flows just fine, is the only improvement I can think of and maybe reversible so it's even easier to clean. Those aren't really dislikes as much as just suggestions for improvement on an already good product.
- Great hiking hydration
Likes: Hiking up a mountain and quenching your thirst at the same time is fantastic with this system. Great job in delivering water while keeping momentum on the trail.
Dislikes: The bottom of the bag got flattened out in a fully packed backpack and slowed water delivery, but a few shakes to loosen the packed items helped fix this.
