Product Information

Organise your entire week of travel, daily business kit, and mobile tech with the exceptional versatility of the BANGE BG-1908 Expandable Travel Backpack. Masterfully designed for city professionals, active hikers, and frequent flyers who want to break away from the restrictions of rigid suitcases, this premium bag reshapes itself to fit your itinerary. It easily adapts from a neat, compact daypack into a high-capacity luggage holdall, allowing you to walk straight out of the office and onto an international flight with confidence.

The crown jewel of this heavy-duty rucksack is its massive zip-activated 22-litre to 45-litre expandable main chamber, paired with an independent 15.6-inch tech compartment and a specialised wet/dry isolation zone. For your standard morning commute or university routine, the bag zips down into a crisp, low-profile frame that slots beautifully under train seats. When it is time to set off for a 5-to-7-day adventure, simply release the expansion zip to unlock a wide-opening wardrobe core that cleanly holds up to 8 changes of clothes.

  • Adapts from 22L to 45L: A clever expandable framework that instantly doubles your packing volume to handle everything from brief commutes to week-long trips.
  • Heavy-Duty Waterproof Build: Crafted from premium, rubberised PVC-coated Oxford fabric and fitted with genuine YKK zips to block out driving rain and morning mist.
  • Smart Wet/Dry Separation: Features a dedicated internal pocket lined with waterproof material to isolate damp swimwear, towels, or cosmetics from your clean shirts.
  • Cushioned 15.6-Inch Tech Hub: An independent, shock-absorbing rear bay engineered to isolate your laptop and iPad from the rest of your luggage.
  • Concealed Anti-Theft Pocket: A hidden security sleeve sitting flush against your spine to keep your passport, phone, and wallet entirely safe in dense crowds.
  • Airflow Shoulder Harness: Outfitted with breathable, multi-panel mesh back padding and an adjustable chest buckle to distribute heavy loads evenly.

The BANGE BG-1908 handles demanding cross-city treks, airport terminal rushes, and outdoor hiking trails with absolute ease. Its softback architecture retains its tailored, smart silhouette even when fully packed, ensuring you always present a sharp profile wherever you arrive. The durable outer surface requires practically zero upkeep, allowing you to wipe away trail dust, road grime, or accidental spills with a quick damp cloth.

Inside the pack, a smooth polyester lining forms a gentle, scratch-free barrier for your sensitive electronics and personal documents. A built-in keychain tracker ensures your keys are always anchored exactly where you left them, while fast-access front zip compartments keep your portable power banks and charging leads beautifully sorted. Finished with an integrated luggage trolley strap that slides smoothly over rolling suitcase handles, this unisex daypack adds true practical luxury to your travel setup.

37-liter maximum capacity backpack, brand Bange

At first glance, the first impression is that the material is very well-made and "waterproof" (that is, it can withstand a drizzle, but I wouldn't risk using it in a real rain), and the zippers are of high quality. The backpack has numerous compartments, including a compartment for a power bank and charging your phone (great for travel).

As you can see in the photos, the finish is very well done, and it's expandable. It has a specific lined pocket for wet items, which is great for used clothes, for example, or something damp (obviously to be removed quickly).

It's really worth the price, I didn't find it cheap, but it delivered everything I expected. Regarding durability, only time can tell. The 37L one has the size of a regular backpack when closed, it doesn't feel awkward on your back, and it seems to be quite spacious when opened. The outer material is quite thick and seems durable, the inner material also seems to be of okay quality. The zippers, at least now while they are new, are very good. In addition, it has a good number of compartments, the compartment for the notebook is slightly padded, and it even has a small pocket at the back where we lean our back, along with a strap to carry along with the bag. The inside cable is UBS A and because it is hidden with a small zipper inside also. The only caveat is that the size 37L does not have a side pocket for a water bottle, but this can be replaced with the front pocket if it's not an issue for you.

Satisfied with the seller. The order arrived days earlier than indicated. Good delivery person, who called me to arrange the delivery.

I bought the 45L black backpack, and it is truly large. Solid and well-made impression leather. The zippers are very smooth and close well.

It has many compartments to store everything, but above all, it has the capacity to expand greatly. Very happy with the purchase, 10/10. I hope it lasts a long time.

Very nice color, has large pockets, front pockets, for a bottle, for hanging keys, and a hidden pocket, large size very good for cabin travel and even daily life, with work/university things and gym things.

I really liked the bag. I didn't give 5 stars just for one minor detail: in a world where everything is being replaced by USB-C cables, the cable that comes in the bag for the PowerBank's output is USB. If you have a powerbank with USB-C outputs, like mine, you won't be able to use the adapter that comes on the side of the bag.

Another detail regarding delivery is that it is not done by the postal service, but by a courier company. You have to log into the app every day to track the delivery.
