Function equals beauty with Blackburn’s new Wayside Backpack Pannier. I would like to introduce the perfect convertible and comfortable pack for carrying cargo on and off the bike. Designed to quickly transform into a simple pannier, the straps fold into a hidden zippered pouch and latch onto a rack via simple webbing. Water resistant, expandable and including a padded laptop sleeve and external pockets for organization, the Wayside Backpack Pannier is the perfect mobile office on and off the bike.
