This unisex backpack is designed for daily professional and casual use, offering a practical solution for carrying a laptop, work documents, and personal items. Its core construction combines ABS PC for structural definition with Oxford cloth for a durable exterior, finished with a polyester lining. Available in two distinct size options – 15 inches and 17 inches – it accommodates different laptop models and load requirements. With a stated capacity of 20 to 35 litres and a waterproof function, it aims to keep essentials organised and protected from the elements during commutes, travel, or everyday outings, presented in a street-trend style with splicing details.
Features and Construction

The backpack's design focuses on functional durability and a defined silhouette suitable for various daily matching scenarios. It integrates specific materials and a bearing system intended for practical, comfortable use.
Material and Build
The primary materials are ABS PC and Oxford cloth. The ABS PC component contributes to the bag's structured form and shape retention, while the Oxford cloth offers a textured, resilient outer shell. These are combined with splicing elements as a stylistic detail. Internally, the compartment is lined with polyester, a common choice for its smoothness and resistance to light wear. The construction includes a stated waterproof function to guard contents against rain and spills.
Size and Practical Fit
The product is offered in two size variants referenced by screen size: 15 inches and 17 inches. This indicates the primary compartment is sized to fit laptops of those dimensions. The overall capacity is 20 to 35 litres, providing space for a laptop, accessories, documents, and personal items. The curved shoulder straps form part of the bearing system, designed to distribute weight more comfortably across the shoulders compared to flat straps, which is beneficial for daily carrying.
Uses and Placement

Described as suitable for daily matching and applicable to both men and women, this backpack serves a versatile role. Its features align with needs from professional environments to casual, on-the-go use.
Event or Professional Use
For business or professional scenarios, the backpack offers a hands-free alternative to briefcases or messenger bags. The waterproof feature and capacity for a 17-inch laptop and documents make it a practical choice for commuting to the office, attending meetings, or business travel where protection of electronics and paperwork is important. The neutral colour options – black and silver white (8009) – provide a clean, adaptable look for professional settings.
Everyday Home Use
Outside of work, the backpack's 20-35L capacity and street-trend style make it suitable for day trips, weekend activities, or as a daily carry-all. The unisex design and colour options offer flexibility for personal style. The curved shoulder straps and organised space can simplify carrying gym gear, study materials, or shopping items, making it a functional accessory for various daily routines.
