Important Notes
The backpack is not recommended for extremely heavy loads exceeding typical carry-on limits due to structural design constraints. Always check current airline regulations before flying, as policies may vary by carrier.
To maintain performance, avoid prolonged exposure to extreme moisture; although the fabric is water-resistant, full submersion should be prevented.
The package includes the main backpack unit and two toiletry bags only—no additional accessories are provided unless specified otherwise.
