Thanks to another forum member and a trade, I now have an adorable Nordic/Steel Synapse 19. To keep my Steel/Wasabi Synapse company. Overkill? Maybe, but I re-homed another bag I wasn't using, and both of these backpacks are very useful. I can also see lending one of them out in certain travel situations while I use the other one, or picking one depending on the clothes I'm wearing.
I think the Nordic is a really nice color; everywhere, but particularly on the smaller bags.
Today's has my gym clothes (without shoes), Side Effect, first aid kit, iPhone in battery case, iPad, Jottbook journal, two sets of keys, flashlight, pens, train pass, and extra scarf.
