I have a question.....I was wondering if you use your BBags seasonally by colors? Do you live in a climate where you feel like you can carry all of the different colors of your bags all year long? Or do you just carry the same one all the time regardless of weather or temperature? I live in Minneapolis and it is literally 8 below today. My Red BBag seems a little too RED for today. Now I really need a Black BBag.... I feel like I need lots of colors to be able to deal with the weather in my city. This is going to be a really expensive issue to deal with .... .
