Vannpose

Vannpose, a term used in Norwegian and Danish, literally means “water bag.” It refers to a flexible container designed to store and transport drinking water. Vannposer are typically made from durable plastics or elastomeric materials and come in a range of sizes, commonly from about 0.25 to 3 liters. They are used in outdoor, military, and emergency contexts where portable water is needed.

In many cases a vannpose is part of a hydration system mounted inside a backpack. This configuration uses a connected drinking tube to provide hands-free hydration, which is convenient for hiking, cycling, and other activities. Features often include a wide mouth for easy filling and cleaning, a leak-proof cap, and a removable hose or bite valve. Many models are collapsible or foldable for compact storage when empty.

Applications and maintenance are straightforward. Vannposer are used for travel, camping, sports, and disaster preparedness. Proper care involves regular cleaning with warm water and mild soap, thorough drying to prevent mold, and inspection for wear or leaks. Material safety should be checked; some plastics are rated for certain temperatures and cleaning agents, and exposure to extreme heat can degrade the bag.

Terminology and usage vary by country. In English, the related term hydration bladder or hydration reservoir is commonly used, while vannpose remains the standard word in Norwegian and Danish contexts. See also hydration system, hydration bladder, and water bottle.
