asics / ASICS Trail Running Pack / Running Bag -------------------- Found while cleaning. It's old. There are no noticeable scratches or stains, but the design is old-fashioned. Some of the silver parts of the back (images 3 and 4) show signs of aging. The inner fabric, etc., has not undergone hydrolysis. (Images 15 and 16) Inside the zipper at the bottom, is it perhaps a bottle holder...? When opened, it's cylindrical, and there's a thick rubber band in a cross shape inside. I'm not sure how to use it. (Images 10, 11, and 12)
