The retail price is $12.99, says so right on the packaging so how Amazon charges from $13.14 up to $16.99 depending on color is beyond me. The bag is great quality and my straps are nylon like the picture shows not rope like some had received. I can fit running shoes, towel, change of clothes, water bottle, a book, my purse and a snack in here very comfortably. NIcely made, not cheap.
