Outdoor Gear Lab Editor's Choice Award

"Stealing the show, the new and improved Platypus Big Zip Evo is our new favorite hydration bladder! The previous design saw a complete facelift that took it from zero to hero (we weren't very impressed with the older version in the past). It has a new bite valve and hose, various connector points and reservoir that offers much better durability and ease of use. While it's not as light as the Geigerrig Hydration Engine, our previous Editors' Choice winner it has a reservoir that is burlier and more reliable. It offers a faster rate of water flow and a better taste. Our only caveat is it's a wider profile that isn't compatible with super narrow backpack sleeves. Ladies and gentlemen, introducing our new, favorite hydration bladder that will keep you hydrated all day long."
