Yup, this is the original (improved, of course) dry bag designed and made by NRS founder Bill Parks.  Back in 1977 the first Bill's Bags were orange - now you get a choice of colours, but the bag remains essentially the same.  Made of durable PVC/polyester with a fold down StormStrip closure, this bag will keep your gear dry.  It's got padded shoulder straps for portaging and the harness is removable.
