Product Overview

The BANGE 35L Travel Backpack is a smart, expandable carry-on solution built for travelers, professionals, and weekend adventurers alike. Designed to meet airline carry-on standards, it fits comfortably under most airplane seats, helping you skip checked baggage lines and move through terminals with ease. With a versatile capacity that expands from 22L to 35L, this backpack adapts to your needs—whether you’re packing for a quick overnight trip, a 5–7 day business journey, or a weekend getaway. It’s equally suited for daily commutes, offering secure storage for a 17.3-inch laptop, travel essentials, and personal items. Crafted with waterproof materials and thoughtful organizational features, it keeps your gear protected, accessible, and neatly arranged no matter where your day takes you.

Key Features

Expandable Design: The backpack starts at a compact 22L for everyday use and expands to 35L with a simple zipper release. This flexibility allows you to carry just what you need for short trips or add extra space for longer journeys or bulkier items like shoes or jackets.
Dedicated 17.3-Inch Laptop Compartment: A padded, separate sleeve securely holds large laptops up to 17.3 inches, preventing shifting during movement. The compartment is lined with high-quality waterproof PVC material, offering reliable protection against rain and accidental spills—ideal for commuters and remote workers.
Dry-Wet Separation Pocket: A specialized interior pocket isolates damp or wet items such as toiletries, swimwear, or cosmetics. This keeps your dry clothing and electronics safe from moisture, making it perfect for gym sessions, beach trips, or post-shower travel.
USB Charging Port: An integrated external USB port allows you to charge devices on the go. Simply place your own power bank inside the bag and connect it to the built-in cable—then charge your phone or tablet from the outside without opening the backpack. (Note: power bank not included.)
Luggage Strap: A convenient rear strap lets you securely attach the backpack to the handle of a rolling suitcase. This makes navigating airports, train stations, or city streets much easier when managing multiple bags.
Waterproof Front Panel: The front face is constructed with durable PVC material that repels water, shielding your laptop and electronics from light rain, splashes, or spills during transit.
Multiple Compartments & Organizational Pockets: Includes a spacious main compartment for clothes (fits 5–8 pieces), a front section for books, tablets, and accessories, and various internal pockets to keep smaller items like chargers, pens, and keys neatly organized.
Comfortable & Durable Construction: Reinforced stitching at stress points, thick padded handles, and smooth, explosion-proof zippers ensure long-lasting daily use. The shoulder straps feature a bandage-style connector near the chest buckle, useful for attaching small accessories like carabiners or pouches.

Benefits & Use Cases

This backpack is ideal for frequent travelers, digital nomads, students, and professionals who value organization, durability, and convenience. Its expandable design makes it perfect for weekend trips, business travel, or as a daily commuter bag.

Remote workers will appreciate the secure, padded laptop compartment and the ability to charge devices on the go via the USB port—especially during long commutes or layovers. Whether you’re navigating city streets, hiking trails, or airport terminals, the BANGE backpack delivers practical functionality without sacrificing comfort or style.

Important Notes

The USB charging port does not include a built-in battery—you must supply your own power bank.
While the shoulder straps include a bandage-style loop near the chest buckle, there are no traditional D-rings for attaching gear.
Care should be taken to avoid overloading the expanded compartment, as this may affect comfort and zipper performance.
Package includes the backpack only; no power bank or additional accessories are provided.
