Okay backpack if it stays out of the sun. My little boy has now used this backpack for the entire kindergarten school year with a month left to go. Here in SoCal the children park their backpacks outside the classrooms. The sun has faded this backpack so badly it doesn't even look orange anymore. Also, the sun has done such a number on it that it is desintegrating. It is literally falling apart. Other than that, the wheels, handle zippers etc. are all good. The material is just not sun/fade proof.
