Outdoor bags are bags designed for outdoor activities such as hiking, camping, trekking, climbing or hunting. These bags are rugged, weatherproof, and comfortable to carry for long trips and rugged terrain.

There are many types of outdoor bags, including duffel bags, canvas backpacks and tactical bags. They typically feature multiple compartments, durable zippers, adjustable shoulder straps, and padded back and shoulder supports. Some styles are compatible with water bag systems, come with MOLLE webbing for securing gear, and waterproof materials to protect the bag's contents from inclement weather.

They are used to carry essential gear such as clothing, food, water, tents, sleeping bags and tools, helping users stay organized and prepared in the outdoors.
