One of the reasons I almost always end up buying Tom Bihn bags is that I know that I can clean them.
Nothing makes me more annoyed than when I have some product that obviously is designed to be used in situations where it will get dirty or sweaty can’t be cleaned.
All of the bags I use when I go back and forth to the office or when I go down town get dirty. The back usually get sweaty and the front get all kinds of dirt on it.
As is typical if you bike or skateboard.
I clean mine when I can see that they are dirty, usually most visible in the area that goes against my back, where it often gets wet and sweaty when it’s hot or if I’m skateboarding over longer distances.
I just make some soapy water, soak the bag in it, flush it in clean water until all the soap is gone and then I just get it drip off in the shower before letting it air dry somewhere else.
The whole process usually takes longer than a day but not by much.
