[Patented Technology] MUJI's original shoulder straps reduce shoulder strain. When carrying heavy loads, the weight is distributed across the entire width of the shoulder straps. This design reduces the feeling of excessive weight and prevents the straps from digging into the shoulders, thereby providing a "shoulder strain reduction" effect. Patent No. 6445744: Patent for backpack shoulder straps and a backpack equipped with them. A divider pocket has been added in front of the PC storage pocket, and a belt has been added for attachment to a carry-on bar. The fabric uses recycled polyester and is water-repellent. This is the navy color, which is no longer available. Used approximately 20 times.
