This Jinshengsi schoolbag is a practical choice for students and commuters who need to carry a laptop and daily essentials. The medium-sized backpack (20L or less) fits a 15.6-inch computer comfortably, while the built-in USB charging port allows you to charge your devices without unzipping the bag. Made from waterproof and wear-resistant polyester, it offers reliable protection against light rain and everyday scuffs. The bag is available in three colours – dark gray, light blue, and gray – and features a casual, plain style with colour-contrast detailing.

Features and Construction

The backpack is built with attention to everyday practicality. Its polyester fabric is both breathable and resistant to wear, helping the bag maintain its appearance over time. The medium-soft structure keeps the bag flexible but supportive, while the soft handle and air cushion straps make carrying comfortable even when the bag is full.

Material and Build

The outer fabric is 100% polyester, chosen for its water resistance and durability in daily use. The lining is also polyester, providing a smooth interior that protects your belongings. The bag has a medium-soft hardness and a plain pattern, giving it a clean, low-profile look.

Size and Practical Fit

This medium backpack has a capacity of 20 litres or less, making it ideal for a 15.6-inch laptop, books, and small personal items. The internal compartments include a dedicated computer pocket, a zipper pocket for valuables, a mobile phone pocket, and an ID pocket. The main opening uses a sturdy zipper for secure access.

Uses and Placement
