I considered dark grey for the bag material, but thought screenprinting large white and tan areas onto it might not work well. They tend to be pretty resistant and easy to clean off! I've used general cleaning wet wipes for bags I've used and haven't had any issues with scuffs or damaging screenprinting or anything. The part of the bags that is most likely to be affected by scrapes would be the clear window, but that has held up well with my crow bag that I've used consistently for the past year!
