Each one looks awesome. I currently use the Everyday Messenger Bag - just as intended, every day. And while I do have some issues with it, it has proven to still be my favorite choice.

Now, they give us 2 backpacks to choose from, a tote and a sling. Since a lot of people have been asking for a backpack, myself included, they produced two different sized backpacks. I went for the 30L myself, but I may add a 20L later...

So many good choices...
