This is the early version of the y-pack, made in Colorado. I used this for a bit; and it shows wear. I tried to show this in the pics. there is some staining on different panels; and on the bottom. I used this while riding a bike in the rain. I washed it in a machine on gentle, and air dried. I didn't try anything more aggressive to clean. I took patches off of it; and you can faintly see where they were.
