I am always on the search for a great commuter bag. Getting my stuff back and forth from work with ease is important. I have now owned and tested several bags designed for commuting and there are things to love about each of them. I will be focusing on the STM Linear Medium Laptop Shoulder Bag in this article. This bag has proven to me over and over that it was designed to handle the daily abuse of commuting. We are also giving away a STM Arvo iPhone 5 case to one lucky reader, check it out below the review.
