Abstract: A disposable, hydration pack intended, in a preferred embodiment, for use within a back pack or similar receptacle is disclosed. A gel filled ice pack surrounding the bladder of the pack allows for chilling of the contents of the bladder. In a disposable embodiment, the hydration pack may be pre-packaged with an energy beverage concentrate. A flexible, thin walled, disposable, or semi-flexible straw, passing through the wall of the bladder or through the cap of an access cap, delivers a beverage from the pack to the mouth of a user without the need for bringing the container of the pack to the region of the mouth. In an alternate embodiment, a belt attached to the bladder allows a user to strap the pack around his waist or over his shoulder.
