AS2OV Backpack AS2OV Rucksack X-PAC × CORDURA DOBBY 305D 061400-x (AS2OV-061400-x-10) It has a rain hood, storage for smartphones and earphones, a PC pocket, and the important parts use cowhide and a white X-Pac material, a special material that combines waterproofness and strength, making the overall quality very high. There are too many other features that I don't understand well, so please look at the images. I only used it once for a trip (2 days of sightseeing in an urban area). It was too professional for me, so it's been in the closet ever since. Capacity: 44L Size: W300 x H500 x D150mm Material: DOBBY CORDURA 305d fabric, Vegetable Tanning Leather Country of Origin: CHINA Description X-PacR NYLON210d fabric, which has flexibility and water resistance, is used for the pocket area. X-PacR is a special 3-layer structure (3-layer) made by bonding three types of materials: outer fabric + thread (fiber) + back fabric using a special method, and is a lightweight and durable material. The main body material uses CORDURAR 305d fabric, which uses 305d special polyester yarn for both the warp and weft, providing strength against friction, tearing, and abrasion. By applying twice the amount of PU processing to the back of the fabric than usual, the fabric has a moderate volume. The interior has storage space for PCs, etc., and uses a brushed material and thick cushioning material to protect electronic devices securely. In addition, the back and shoulder pads have solid cushioning material, and the shoulder pads have pockets for quick access to mobile phones and keys. The material is unified in all black, and the AS2OV original brass plate finished with nickel plating is a key point.
