Peak Design Travel Backpack 45L Black BTR-45-BK1 This is a Peak Design travel backpack. I'm selling it because I don't use it as often anymore. I mainly used it for my camera, so I didn't use it in a way that put a lot of stress on it. All the zippers function properly. I don't have the original large box, so I plan to wrap it in a large plastic bag for shipping. Below is a description of the product: 【Product Features】 ■ You can compress the top of the bag to reduce the capacity by 10L, and open the zipper on the surface to increase the capacity by 5L, allowing for size adjustment. ■ Side pockets for storing water bottles and tripods. ■ Laptop sleeve can store laptops and tablets. ● External dimensions: H56 x W33 x D23-29cm ● Storable PC size: H40 x W30 x D2.5cm ● Storable tablet size: H24 x W19 x D1.5cm ● Capacity: 35-45L ● Weight: 2.05kg
