When carrying heavy loads, the weight is distributed across the entire width of the shoulder straps. This reduces the feeling of excessive weight and prevents the straps from digging into the shoulders, alleviating pain. This provides the effect of "reducing shoulder strain." Patent No. 6445744: Patent for backpack shoulder straps and a backpack equipped with them. The top opens, allowing you to easily see inside. A belt has been added so it can be attached to a carry-on bag handle. The fabric uses recycled polyester and is water-repellent. Size: 50cm (height) x 30cm (width) x 18cm (depth) Color: Black系 (Black-based) Condition: No stains or tears.
