Know before you buy
The T-B9815 features a detachable strap system that allows you to transition between backpack, shoulder, and crossbody carry modes. You can easily adjust or remove the straps based on whether you need a hands-free commute or a more professional side-carry look.
Yes, the main compartment is specifically designed to accommodate laptops up to 17 inches. It provides a spacious interior, though we recommend using a slim laptop sleeve if you prefer extra padding for your device.
The backpack is crafted from 900D water-resistant material, which is highly effective at repelling light rain and protecting your belongings from splashes. While it is durable and easy to clean, it is not fully submersible, so it is best to avoid heavy downpours or complete immersion.
The zipper groove design is engineered to reduce friction, allowing for a smoother opening and closing experience. Additionally, this structure provides better impact resistance, which helps prevent the zipper teeth from separating or jamming over time.
At approximately 1.25kg, the bag is lightweight by design. While it offers a 25L capacity, the comfort level will depend on how you distribute the weight, but the versatile strap options allow you to shift the load between your shoulders and body to reduce strain.
