MSR Dromedary Bag Water Reservoir - Rugged Collapsible Carry

Our review of the MSR Dromedary Bag Water Reservoir finds it best suited for expedition-minded hikers, mountaineers and overland travelers who need a tough, high-capacity water carrier that packs small when empty. The single biggest reason to buy is durability combined with packability: the bag's 1,000-Denier exterior and a laminated, BPA-free food-grade lining mean it stands up to abrasion, freezing and repeated use while collapsing flat for efficient stowage. In short, this is a storage-first water reservoir built to survive heavy field use rather than a lightweight day-hike bladder.

Key Features

• Heavy-duty exterior: The 1,000-Denier shell resists punctures and abrasion so the bag will survive rough handling on multi-day expeditions.
• Food-grade lining: The laminated BPA-free lining improves taste and is intended to hold potable water safely for extended trips.
• Completely collapsible: When empty the Dromedary Bag flattens for compact packing, saving space in a pack or duffel.
• 3-in-1 cap: The included cap lets you fill, drink and pour with fewer spills and makes water transfer simpler in camp and on the trail.
• Attachment points: Streamlined webbing and strategic grommets allow secure pack attachment or hanging from a tree to gravity-feed or suspend a shower accessory.
• Accessory compatibility: Compatible with MSR Shower and Hydration Kits to add versatility for washing, drinking, or group use.

Who It's For

The Dromedary Bag suits backcountry teams, mountaineering parties, basecamp crews and overland travelers who need robust, large-capacity water storage that can be left on the ground, hung for gravity feed or forced into service as a makeshift shower. Its toughness and freeze resistance make it a practical choice for mixed-season expeditions and long trips where resupply is limited.

Those who should look elsewhere include ultralight day hikers and runners who prioritize minimal weight and small-volume hydration packs; the Dromedary Bag is built for durability and capacity rather than shaving every ounce.
