Recently, we were lucky enough to speak to Yang Dong about his extensive photography of the Great Wall of China and were impressed by his dedication to his craft. We decided to send him our 35 Rucksack to get his views on the bag and how it might work for him on his travels as a photographer. The interview below was originally written in Chinese and has been translated to English. Yang Dong with his 35 Rucksack. Photo by Yang Dong Hi! I am Yang Dong, a photographer who takes pictures of the Great Wall. I spend one third of my days on the Great Wall every year. I have been taking pictures of the Great Wall for seven years, taking more than 500,000 photos and 40TB videos, covering a distance of more than 100,000 kilometers from the eastern end of the Great Wall in Dandong Hushan, Liaoning province to the western Border of Xinjiang. Covering more than a dozen provinces and cities I have recorded images of the Great Wall of Qin, Han, Sui, Tang, Song, Jin and Ming dynasties. Some time ago, I happened to see Billingham's 35 Rucksack classic backpack launched in a new color -- navy blue. Because I like blue, I immediately wanted this bag. The 35 Rucksack is available in a variety of other colors such as Sage, Khaki and Black. Billingham is a British brand, and all bags and accessories are made at their Cradley Heath factory in the West Midlands. The bag features a waterproof canvas body, plenty of vegetable tanned leather and brass buckles. Each hide of leather, piece of hardware and every detail of the material is carefully selected. Then through a combination of machine cutting production and hand sewing the bags are completed. They ship their bags from the UK and the moment I received it, I thought the bag was a work of art! So I couldn't wait to take it to the Great Wall for a walk. Photo by Yang Dong Appearance Photo by Yang Dong The appearance of this bag is very good! The retro classic shape is very fashionable, and at a glance left me feeling enchanted. The front of the bag adopts a classic British design, elegant in style. Canvas fabric and top grain leather material create a lightweight super practical backpack. More than 90% of the backpacks on the market are not waterproof. This bag has three layers of carefully made waterproof fabric, which is not only durable, but also extremely waterproof. As long as the fabric is not damaged, it is waterproof for life. Photo by Yang Dong The front pocket is brilliant. Not only elegant, but also very practical. It can be used to store some small items, as well as a mirrorless camera, flash and water cups etc. Photo by Yang Dong The side of the bag is simple, fashionable, clean and neat. Photo by Yang Dong The back adopts the same material design and is equipped with ergonomic shoulder straps to enhance the comfort on the shoulder. It feels comfortable to use, cares for the shoulders, is durable and thoughtful in design. Padded Inserts Photo by Yang Dong The Padded Insert of this bag is brown and is made of high-quality fabric and foam. It is elegant in appearance and careful in workmanship, with excellent scratch resistance and wear resistance protection. Photo by Yang Dong The padded insert has dividers, which can fully protect the equipment in the bag. There is no need to worry about grinding and scratching the surface of the camera and lens during walking and shooting. Photo by Yang Dong When you don't need to carry your device, you can remove the padded Insert and turn it into a stylish casual bag for you to use on the road, which is the biggest highlight of this backpack. Capacity introduction and daily carrying equipment display Photo by Yang Dong 35 Rucksack is of a reasonable size and capacity. You can put your SLR camera and three lenses in the Padded Insert.

Also the press-studs on the back wall of the bag and the back of the padded insert will rub against the laptop in this position.

The shoulder strap links are carefully and solidly stitched. Photo by Yang Dong The built-in zipper has an anti-theft appearance. The double zipper works smoothly and unimpeded. The golden zip is made of metal, and the Billingham logo is beautifully carved to highlight the noble status symbol! Photo by Yang Dong The brass buckle at the connection between the shoulder strap and the bottom of the bag, is not only beautiful, but also more solid and safe, and can better cope with bad weather as brass does not rust.

Photo by Yang Dong The shoulders are also designed to lighten your load, with high-end fabrics and you don't need to worry about fraying your cotton clothes during long walks. My feelings of the bag For photographers, the first thing we need is a good photo bag. The most important thing about a camera bag is its protective performance, and the comfort of carrying it. Billingham 35 Rucksack is a typical good-looking backpack. It can be used for photography, leisure, work, travel, and for me it is very convenient. It doesn't seem very big, but it can hold a lot of things. Using a backpack feels much more relaxed than a shoulder bag and is just as comfortable as wearing clothes. Soft padded insert plays a good role in protecting valuable equipment. The exquisite materials feel very good! High-quality leather and metal ring buckle make the bag look better and more memorable. The British retro design is very versatile and both men and women can use it. How could such a bag not make you feel good? 35 Rucksack is my favorite photography backpack by far!
