The BANGE Business Trip Travel Waterproof Extension Backpack expands from 22L to 37L via a perimeter zipper. Waterproof Oxford fabric shields internal electronics from liquid penetration. This 1.1kg unit accommodates a 15.6-inch laptop and opens 180 degrees for flat-lay packing.
Key Features
- Expandable 22-37L Capacity: Depth increases from 16cm to 28cm using side zippers. Fits three days of clothing without needing a separate suitcase.
- Waterproof Oxford Fabric: High-density textile prevents moisture ingress through the shell. Protects gear from heavy sweat and humidity during outdoor transit.
- External USB Port: Integrated charging interface connects to an internal power bank. Powers mobile devices while walking without unzipping the bag.
- 180° Opening Angle: Main compartment unfolds completely for full interior access. Simplifies airport security checks and organizes clothes like a suitcase.
- YKK Brand Zippers: Heavy-duty Japanese hardware resists teeth separation under tension. Won't jam or break when the bag reaches maximum expansion.
- Breathable Mesh Back: Multi-layer foam padding with air-flow channels. Reduces heat buildup against the spine during long commutes.
