I have a Lo & Sons OG and the issue I have with it is that there's no way to lock it. Considering this is a travel bag, that surprised me. I'm not comfortable traveling with an unlocked bag - I travel alone frequently and have no one to watch my bags in an airline lounge or on a train if I need to go to the ladies room without wanting to schlep my stuff with me, for example. As a result, I'm not using it much and am thinking about consigning it.
