Purchased in October 2025 and used once. The design is good, and it's incredibly user-friendly. It's an 80L large-capacity backpack with an expansion function. Despite its simple appearance, it's highly functional. The pockets for storing small items are the type shown in photo 6. It's not the pocket type shown in photo 1. Items can be organized and stored, making it easy to find and retrieve them quickly, eliminating the "where did I put that?" problem, which was very convenient. It was also suitable for carry-on luggage. - Model: Upgrade - Capacity: 80L - Expandable: Large capacity expansion of approximately 50L - Expansion Rate: 25% Thank you for viewing.
