Hydration system with improved fluid reservoir

摘要

Hydration systems with improved fluid reservoirs. The reservoirs include a fill port with a neck having an opening through which drink fluid may be inserted into the reservoir's internal compartment. The hydration systems also include a drink tube through which a user may draw drink fluid from the reservoir. The hydration systems further include a cap that selectively seals the opening. In some embodiments, the opening has a diameter of at least 2.5 inches. In some embodiments, the opening has a diameter of at least 3 inches. In some embodiments, the cap is threaded onto the neck. In some embodiments, the hydration systems include wrench assemblies and/or support members that extend around the neck and which may be selectively used to assist in sealing or unsealing of the cap onto the opening and/or to position the reservoir.
