When I was in school, I used to go through a backpack a year, if not two. When you're buying from MEC, you need to make sure it's in a colour you like, because you won't have an excuse to buy another one for twenty years.
My last backpack (obligatory Browning reference: painted on the wall, etc. etc.) was bought eight years ago and has accompanied me to classes, to archaeological excavations, to the grocery store.
It has faded a little, and the mesh side pockets have lost their elasticity, but I'll probably make my (as yet unborn) children take it to school some day.
MEC makes quality goods, and they're good to browse for gifts - for your outdoorsy friend or for that new exercise regimen you're sure you'll start if you only have sufficiently inspiring equipment.
