Wearing your bag in different ways is kind of difficult when it’s only designed to be worn one way. Topo Designs solves that problem with its new transforming Mountain Briefcase. The bag is designed with a 3-way carrying system that allows it to be a briefcase, a backpack, or an over-the-shoulder bag so you can use it for business during the week and travel for the weekends. There are three colors available now on the Topo Designs website.
