Stay organised and protected during your daily routine with this portable USB business computer bag, designed for professionals, students, and travellers who need reliable storage for a laptop and accessories. The waterproof leather exterior ensures your electronics stay dry in light rain, while the integrated USB port lets you charge your phone or tablet without unzipping the main compartment. With a generous 20 to 35L capacity and a thoughtful carrying system, this backpack balances practicality and comfort for work, school, or weekend trips.
Features and Construction

Built with everyday use in mind, this backpack combines water-resistant materials with a smart bearing system to reduce fatigue during longer carries.
Material and Build
The outer shell is made from Derm, a waterproof leather-like material that repels moisture and resists scuffs. Inside, a polyester lining adds a smooth, durable surface that protects against scratches. The bag is available in two classic colours—black and gray—to suit different professional or casual styles.
Size and Practical Fit
With a capacity range of 20 to 35 litres, this backpack can fit a standard laptop, a tablet, notebooks, a water bottle, and other daily essentials. The single main compartment opens wide for easy packing, while internal organisation keeps smaller items accessible.
Uses and Placement

Whether you are commuting to the office, heading to class, or travelling for a short trip, this bag adapts to your load requirements.
Event or Professional Use
Its water-resistant outer layer makes it suitable for outdoor business events or conferences where weather is unpredictable. The USB port is particularly handy for professionals who rely on mobile devices throughout the day.
Everyday Home Use
For students or remote workers, the backpack doubles as a carry-all for gym clothes, lunch, and tech gear. The air pillow belt system distributes weight evenly, making it comfortable during longer walks or public transport commutes.
Benefits and Buying Value

This bag offers straightforward value through its combination of water protection, ergonomic support, and practical features.
Reuse and Low Maintenance
The waterproof leather finish requires only a quick wipe with a damp cloth to stay clean. There is no need for special treatments, and the polyester lining resists odours from regular use.
Why Choose This Product
If you need a single bag that handles both wet weather and daily tech storage, this computer bag provides a reliable solution without unnecessary extras. The air pillow belt and USB integration add convenience without complicating the design.
