Completely collapsible for superior packing efficiency, MSR's burliest medium-to-large capacity water storage and delivery systems are perfect for everything from alpine- to road warrior-style expeditions. Armed with incredibly tough 1,000-Denier exteriors and now laminated with an improved BPA-free food-grade lining for better-tasting water, these bags can handle freezing and the abuse inflicted by expedition crews and hardcore adventurers.

MSR's Hydration Kit accessory adds do-it-all versatility, and the new svelte 3-in-1 cap lets you fill, drink, and pour with greater ease. Perimeter webbing allows for easy lashing and hanging, and thanks to that bombproof construction, these Droms can take a beating no matter where you store them.
