I like the color, which gives this backpack a unique look. The overall construction appears to be well made and durable. I also appreciate that it is made from 100% recycled bottles, which is a positive environmental feature. One area for improvement is the side pockets designed to hold a tumbler or water bottle. Many bottles are now larger in diameter, and the current fabric is too tight to accommodate them comfortably. I would recommend using a black stretch webbing material for the side pockets to provide more flexibility and allow them to fit a wider range of bottle sizes.
