Reliable gear is critical in the backcountry. That's why these burly water carriers are built with a tough 1,000-denier exterior. Freezing temperatures? This MSR® Dromedary® can handle it. Filled with boiling water? Yup, it handles that, too. And the new svelte 3-in-1 cap features a large filling cap, a smaller pouring cap, and a flip-up nozzle for drinking from, or washing hands. Laminated with an improved BPA-free food-grade lining for better-tasting water. Completely collapsible for superior packing efficiency.
