Men's PU Leather Backpack 20-35L Large Capacity Business Computer Bag in Black with Waterproof Function and Polyester Lining for Work and Travel
Men's Black PU Leather Backpack with 20-35L Capacity

This men's backpack is built around a simple brief: carry a computer and daily business items in a bag that uses PU leather on the outside and a polyester lining on the inside. The stated 20-35L capacity gives a clear range for buyers who need space for a laptop, paperwork and personal items. The black colour keeps it suitable for office, commute and travel use. A waterproof function is listed for the PU material, which helps with light rain exposure. The pack is supplied as a single backpack in black.
Features and Construction

The main construction facts are the PU leather outer, the polyester lining and the stated waterproof function. These details matter because the outer material affects how the bag handles weather, while the lining affects the interior feel. The 20-35L capacity is the only size figure given, so it is the main guide for what the bag can hold.
Material and Build
The outer is made from PU leather, a synthetic leather-look material. The source lists a waterproof function for the bag, which supports use in light rain. The lining is polyester, a common textile used for bag interiors because it is smooth and easy to wipe. No seam-sealing, coating rating or waterproof depth is provided, so the waterproof claim should be understood as stated rather than as a tested performance level.
Size and Practical Fit
The stated capacity is 20-35L. That range is large enough for a computer, charger, notebook and other business items, depending on how the bag is packed. Because no height, width or depth measurements are given, buyers should treat capacity as the primary sizing guide. The black colour and leather-look finish keep the bag visually suitable for professional settings.
Uses and Placement

This backpack is aimed at men who need one bag for work, commuting or short travel. The PU leather look works in business settings, while the 20-35L capacity supports computer carrying and everyday items. It can also be used as a general day bag where a larger carry space is useful.
Event or Professional Use
For office work and business travel, the backpack offers a single main carry space in the 20-35L range. The black PU leather outer gives it a formal enough appearance for meetings, while the waterproof function helps with wet commutes. It is not described as a specialist camera bag or tool bag, so its role should be kept to general business and computer carrying.
Everyday Home Use
Outside work, the bag can hold daily items such as a laptop, documents, books or a change of clothes within the stated capacity. The polyester lining makes the inside easier to wipe clean than an unlined bag. The waterproof PU outer adds a practical layer for everyday use in changeable weather. No internal pocket layout is given, so storage organisation is not confirmed.
Benefits and Buying Value

The main buying value comes from the combination of a leather-look outer, a stated waterproof function and a 20-35L capacity in one backpack. These are practical features for anyone who wants a single bag for business and computer carrying. The package contains one backpack, so buyers know exactly what is supplied.
Reuse and Low Maintenance
PU leather and polyester are both easy to wipe with a soft, damp cloth. That makes the bag straightforward to keep clean between uses. The waterproof function supports use in light rain, though it should not be treated as full submersion protection. Storing the bag in a dry place helps keep the materials in usable condition.
Why Choose This Product
Choose this backpack if you need a black, leather-look bag with a stated 20-35L capacity and a waterproof function for business or computer carrying. The PU leather outer and polyester lining are the confirmed materials, and the pack is supplied as one backpack. Since only the capacity is given, buyers who need exact dimensions should note that no further measurements are provided in the source data.
