Just the right size for school and a night or two on the road. I think it repels water but not downpours, light rain and not for a long period of time. should be perfect for school. wide strap and back. tons of branches. should work perfectly for school. I actually bought this backpack along with a lightweight wagon for my kids as all wheeled backpacks were flimsy and if the bag broke first the wheels had to be snapped in too. but as we have two separate ones we have the flexibility to keep one. the wagon also fits in a backpack (yes, it is so small and light). if you are interested handcart https://www.amazon.com/gp/product/B019SMHFSU/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1. All in all my kid loves it!
