Important Notes

While this backpack is constructed to be durable and resistant to moisture, it is not fully waterproof. Users should still take precautions against prolonged exposure to heavy rain or submersion. Always verify current airline carry-on policies before travel, as size limits may vary by carrier. No additional accessories or components are included unless explicitly stated in the packaging. Care should be taken when expanding the main compartment to avoid overstuffing, which could compromise zipper performance or structural integrity.
