Abstract
Disclosed herein are embodiments for a leak-proof hydration bladder with an improved opening and folding closure mechanism. Embodiments include an opening on a top side of the bladder and a closed bottom side. A strap is attached to a first side of the bladder and extends to a second side opposite. The strap has a closure mechanism that attaches to a second side of the bladder. The bladder includes a hose with access to an inside of the bladder for consumption of its contents. The bladder is made of a plastic material that maintains a substantially leak-proof seal when the bladder is folded from the top and the closure mechanism is closed.
