The quality of the Mackenzie Backpack (Unicorn one) is substandard for Pottery Barn, I would not recommend this. I ordered one less than 2 months ago and it is used by a 4 year old to carry into school, hang on a hook and carry out of school, its not carried around all day or thrown on the floor. It has 3 places where it is worn completely through (in less than 2 months!). Pottery Barn customer service says it is expected normal wear and tear (in less than 2 months!) and will not refund or replace. The material seems to wear through/snag very easily (it did in several places on ours) and the trim/binding is coming unraveled in multiple places as well. I'm disappointed in Pottery Barn for not standing behind their product or providing products with more durable materials than this. Customer Service told me I could order another one for a 10% discount...I will not be ordering another one. I expect a backpack to be made of a material that will hold up under light use for more than 2 months.
