Anybody know anything about the backpack Fjallraven Kanken?

Hey guys, I recently got a free gift box from a website I like (Massdrop, I referred friends) And in the gift box was a backpack called "Fjallraven Kanken". Its a cool little backpack and looks like it could be used for hiking, but I searched the backpack on Youtube and the majority of owners are female or feminine. I am not familiar with the brand but I hope you guys might.

Is the backpack typically used by females and whats the general vibe you get from it? Thanks.
