Computer Bag Inner Bag – Waterproof Laptop Sleeve for 11.6 to 15.6 Inch Devices

This computer bag inner bag offers a straightforward solution for carrying your laptop with confidence. Made from waterproof and breathable polyester, it shields your device from light rain and accidental splashes while allowing air circulation to reduce moisture build-up. The inner nylon lining adds a soft buffer against scratches. Available in a range of sizes from 11.6 to 15.6 inches and seven colour options, this business casual sleeve fits seamlessly into your daily routine, whether you are commuting, travelling, or simply moving between rooms.
Features and Construction

The laptop sleeve is built with practical materials and a clean design that prioritises function without unnecessary frills. Its waterproof polyester outer fabric is breathable, helping to prevent condensation inside the bag. The smooth nylon lining protects your laptop's finish from scuffs and marks during insertion and removal.
Material and Build
The outer layer is 100% polyester, chosen for its water-repellent properties and durability. This fabric allows moisture vapour to escape, reducing the risk of dampness inside the sleeve. The inner lining is made from nylon, which provides a low-friction surface that helps keep your laptop scratch-free. Stitching is consistent and tidy, contributing to a neat overall look.
Size and Practical Fit
This inner bag is offered in six size options: 11.6, 12.5, 13.3, 14.1, 15.4, and 15.6 inches. Each size is designed to fit a laptop with those screen dimensions snugly, reducing movement inside the sleeve. Choose the size that matches your device's screen measurement for the best fit. The sleeve itself is lightweight and slim, making it easy to slide into a backpack, messenger bag, or briefcase without adding noticeable bulk.
Uses and Placement

The business casual styling means this sleeve works well in both professional and relaxed environments. It is a practical accessory for anyone who wants a layer of protection for their laptop without the weight or complexity of a padded case.
Event or Professional Use
For office workers, freelancers, or students moving between meetings and classes, this inner bag keeps the laptop safe inside a larger bag. The waterproof outer provides peace of mind during unexpected showers, and the simple design does not clash with formal or corporate attire.
Everyday Home Use
At home, the sleeve protects the laptop from dust, spills, and accidental knocks when not in use. It can also serve as an organised way to carry your device from the desk to the sofa or kitchen table. The range of colours allows you to match your personal style or bag interior.
Benefits and Buying Value

This computer bag inner bag delivers core protection at a straightforward price point. Its materials and construction are chosen for practical everyday use, reducing the need for frequent replacement.
Reuse and Low Maintenance
Polyester and nylon are easy to care for – simply wipe the sleeve with a damp cloth to clean light marks. The fabric dries quickly, and the sleeve can be reused daily without showing wear. No special cleaning products are required.
Why Choose This Product
If you need a lightweight, water-resistant laptop sleeve that fits a common screen size and comes in several colour choices, this inner bag covers those requirements. It avoids bulk while providing a reliable shield against everyday elements. The combination of waterproof polyester and scratch-preventing nylon lining adds value for anyone seeking basic yet effective laptop protection.
