The size of a hiking backpack depends on the length and type of the hike. For day hikes, a smaller backpack with a capacity of 20-30 liters is usually sufficient to carry essentials like water, snacks, a first aid kit, and extra layers. For overnight or multi-day hikes, a larger backpack with a capacity of 40-70 liters is more appropriate to accommodate additional gear such as a tent, sleeping bag, cooking supplies, and extra clothing. It's important to consider the duration and intensity of the hike when choosing the size of a hiking backpack. **

Yes, a hiking backpack can be considered as carry-on luggage as long as it meets the size and weight restrictions set by the airline.

Additionally, make sure that the backpack can fit in the overhead compartment or under the seat in front of you. **

International business refers to the exchange of goods, services, and capital across national borders, involving activities such as importing, exporting, and foreign direct investment. On the other hand, international management focuses on the coordination and control of resources and activities within a multinational company operating in multiple countries.

In essence, international business is about the transactions themselves, while international management is about the management of those transactions and the associated challenges. **
