Opt for a large checked bag ranging from 80 to 100L. These bags offer generous capacity for long-term travel, allowing you to pack multiple outfits and gear. However, keep in mind that larger bags may have size and weight restrictions, and they can be more challenging to maneuver through airports.

Duffel Bags and Soft Sided Cases

Duffel bags and soft-sided cases provide ample space and flexibility, making them great for long-term travel. They typically range from 80 to 120L and can be filled to your hearts' content. Their flexibility allows you to stuff in as much as possible, but they may not protect your belongings as well as hard-sided cases.

Remember, when choosing a bag, consider your personal preferences and travel style. Some travelers prefer smaller, ultra-lightweight bags for ease of carrying, while others opt for larger bags to pack everything they need. Whatever your preference, choose a bag that complements your travel style and ensures a comfortable, stress-free journey.
