Is a hydration bladder patented?

Short answer: specific designs of a hydration bladder have been patented many times, but "a hydration bladder" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a hydration bladder been patented?” but “has my combination of features been described before?” Drinkware patents cluster around lids, seals, insulation and add-ons; the specific closure or accessory is usually the point of difference.
