From Duslang Leather Backpack Co., LTD., a company founded in 2005 and specializing in the development, production, and sales of laptop backpacks, crossbody bags, chest bags, and other leather handbags, comes the brand DUSLANG. DUSLANG takes leisure, fashion, business, and sports as its themes, aiming for high-end quality in its production. Our products are highly welcomed by customers from all over the world, with an annual sales quantity of about 4.5 million.

The Duslang customer support team is always here for you, providing reliable and efficient warehouse management to ensure that each Duslang backpack is delivered to you in a well-packaged and prompt manner. Our backpacks make the perfect gift for your family, with a range of designs available for you to choose from.

The DUSLANG backpack features an expandable design, allowing it to transform from a 40L daily backpack to a 50L travel or business backpack. This versatility is achieved through an expandable zipper on the side, enabling you to adjust the capacity to suit your needs.

The backpack's roomy capacity and multi-pocket design ensure that your items are organized and easily accessible. With three main large compartments and 11 inner, front, and back pockets, the college laptop bookbag can accommodate a 17.3-inch laptop and a 12.9-inch iPad, along with your other essentials such as textbooks, wallet, and clothes.

Designed with the frequent traveler in mind, the DUSLANG backpack is flight-approved and meets airline carry-on requirements, with dimensions of 2013.79.8 inches. The luggage strap on the back allows you to slide it over your luggage tube, making it easy to transport.

To ensure a comfortable carrying experience, the backpack features a burden-reducing design. The back and chest buckles help distribute the weight, making it less taxing on your back and shoulders, even when the backpack is full.

Lastly, the DUSLANG backpack comes equipped with a USB charging port, allowing you to charge your phone on the go. Simply connect your power bank (sold separately) to the port inside, and you can keep your device powered up wherever you are.

Whether you're commuting, on a business trip, hiking, traveling, camping, or participating in other outdoor activities, the DUSLANG backpack is a versatile and reliable companion that caters to your needs.
