As I haven't bought a themed backpack previously, am I to understand these to be either/or situations? Either slot it as the 44 slot bag or drag it to your cloak slot for appearance. But not both?
And I wanted to ask about the Treeglider's. Are these giant squirrels seen somewhere in Norrath originally? Is there a Druids Gone Wild storyline to explain their existence? 
To your first question--if you equip the bag as a bag, then go to your Options tab in your character window, you have a drop-down menu there that gives you the choice to show your cape, your melee weapons, your equipped bow, or your snazzy new backpack. 
As to your second question---I always did wonder what those women were really up to at the Antonican druid ring out there in the middle of nowhere...
