(57) Abstract

Disclosed is a fluid reservoir shell that provides protection for the fluid reservoir of a personal hydration system. The fluid reservoir shell is rigid and does not collapse easily under external pressure. The fluid reservoir shell is sized to contain the fluid reservoir but still fits in a personal hydration system pack. The shell protects the fluid reservoir and prevents the fluid reservoir from leaking due to excessive external pressure. The fluid reservoir shell disclosed includes a shell top piece and a shell bottom piece, which couple together to enclose the bladder of the fluid reservoir. The fluid reservoir shell provides ready access to the fill port and the drink tube of the fluid reservoir when the fluid reservoir is contained in the fluid reservoir shell.
