non obtrusive
I've carried my black skytrain all over the place, and haven't found the logo patch to be as obnoxious as I would've thought when I was purchasing... ditto for the airboss.
If I'm super cool and get all my chores done (*sigh* why do the contents of my bag turn into a MESS once I unpack from a trip, when they're so ORGANIZED while I travel?), I'll post some pics of my black skytrain tonight.
