I am selling this item because I purchased it but hardly used it. There are no stains, frays, or tears. I am open to price negotiations within reasonable limits. The following is the official website description: This "Seinou Type 1 B" is an advanced version of the "Seinou Type 1." It's a 0.5-DAY bag designed to carry items in addition to hydration. The front helmet holder can store a helmet. The helmet holder uses mesh fabric, which is convenient for storing wet rain gear. The shoulder straps connect to the bag body with webbing, allowing for easier movement of the shoulders while carrying the bag. The bag sits high on the back when worn, minimizing interference with the first line. Custom orders are possible depending on the contents. 【Size】Height 40cm x Width 23cm x Main Storage Depth 15cm Helmet Holder Expansion: Maximum 25cm
