We actually purchased this for school instead of lacrosse. It is the same general size as your standard backpack but much more durable and has LOTS of space for his binders, supplies, etc.Pros:
Spacious, durable, heavy-duty zipper, great supportCons:
Didn't know there was a cross channel inside to hold the lax stick (description said exterior). There is an entrance hole at the top left and an exit hole at the bottom right. The channel goes right through the inside of the backpack. Kinda gets in the way but we are working around that buy using it as a divider for materials. I would think if you are using this backpack for lacrosse it would impede the space for larger gear once you put a stick in there.
