Backpack's glitch
It is because when a human is wearing it they are standing straight up. Everything in this game “Minus SOME cultural” was designed for humans and they just modded it for others races. Backpacks however were just given to humans and slapped onto other races. I feel your pain, I have almost no options for back packs because my charr is being forced to use human designed gear. Guess asking for some skilled artwork for other races is too much to ask.
