I have a Jansport knapsack or backpack ?
Approved answer (verified by Mister Micawber)
It seems like the term "backpack" came into use when they developed hiking packs with aluminum frames, allowing one to comfortably carry a heavier load.
Perhaps serious hikers learned of these before I did. I expect early explorers hired people to "pack" heavy loads on frames on their backs.
I believe currently, the very small packs which students use to carry their books to school, are called "backpacks."
anyone with the name seth or initals SAGL will always be wearing knapsacks.
People are waiting to help.
