MSR Dromedary Bag Water Reservoir - Tough Collapsible Water Storage

In this review the MSR Dromedary Bag Water Reservoir stands out as a practical solution for expedition-style water storage; it is best for groups and long trips where durable, high-capacity liquid carry matters most. The single biggest reason to buy is its rugged 1,000-Denier exterior combined with a BPA-free food-grade lining, which together make it both hardwearing and safe for drinking water. Reviewers should expect a simple, collapsible system that packs small when empty and holds up to freezing and heavy use on multi-day outings.

Key Features

• Collapsible design: Packs down flat for efficient storage and saves space inside a pack or vehicle when not in use.
• Food-grade lining: The improved BPA-free lining is intended to reduce off-taste so water stays more palatable on long trips.
• Rugged exterior: Built with a 1,000-Denier fabric that resists abrasion and stands up to expedition abuse and occasional freezing.
• Pack attachment points: Streamlined webbing and grommets let you lash or hang the bag easily from packs or frames for hands-free use.
• Included 3-in-1 cap: The cap allows filling, pouring, and drinking without needing extra adapters, simplifying camp chores.
• Made in the USA: Domestic construction supports consistent quality control and field repairability for serious users.

Who It's For

The Dromedary Bag is aimed at alpine climbers, backcountry groups, and overland travelers who need a durable, medium-to-large capacity water reservoir that can be hung, lashed to a pack, or used as a gravity-fed source. Its toughness and freeze-tolerant construction also make it suitable for cold-weather parties who may store water in packs overnight.

Those who rely on filter bottles for rapid personal hydration or who need a rigid dispenser for single-person day hikes should look elsewhere, as this item is designed as a group or expedition storage solution rather than a lightweight single-bottle replacement.

Pros & Cons

Pros

• Very durable 1,000-Denier exterior resists punctures and abrasion on rough trips.

Cons

• Some users report mixed experiences with taste and occasional leakage, so careful inspection and rinsing are recommended before first use.
