For a lot of years I just used my kids' backpacks after they retired them from the school year, I usually made sure to buy something plain & dark, black, brown, or green.

About 10 years ago, I decided to treat myself, and bought one from Cabelas. I still have it, still in great shape, and I'm sure I'll still have it in 10 more years. They still make them, and it has plenty of room for all your gear, and then some. It was around $60 I think when I bought mine.
