tldr; Iconic but basic. Style over function, minimal organization. Fashion statement first.

I hate roll-top bags so the one on the right (the Tom Bihn).

They sit too low on my back. Tend to be “droopers” and I like mine up high. I tend to prefer Evergoods and GORUCK for backpacks. I have a Synapse 25 that I need to sell at some point but it just isn’t a fit for me personally. It’s a well made bag though.

This looks really authentic! My Kanken has the same patch, and the same fox button. My Kanken does not have the address line and also seal from Sweden on it. You did note it was older, so that could easily be a difference. The fonts looks identical to my Kanken. I would say it is authentic.

Honestly the Kanken is just a trendier version of the classic jansport with a higher price tag and a cute patch
