Lands end classmate medium backpack. It’s kind of big for a 1st grader but it has held up really well—been used 2 years so far and looks great still. My older kid had the ll bean junior and the fabric was always getting stuck in the zipper…very annoying. We have also owned pottery barn backpacks and they don’t seem as well made (one of the water bottle pouches tore early on, the buckle that goes across the chest came off right away).
