In Finland we have this thing called “keikka”, as in gig (concert), business trip or burglary. For a keikka you need a bag, a suitably sized one with carry handles and shoulder strap, preferably with some basic compartments for organization. And it should be strong enough to carry a heavy load. “Keikkalaukku” (“laukku” = bag) has since decades back established itself as the common Finnish term for duffel bags, gear bags, you know THAT particular type of proper heavy hauling bags. We have been making heavy duty backpacks since before most of our current employees were born, it’s about time we did a proper series of duffel bags too!
Now you’re that much smarter. Good job, Finnish is a damn difficult language to learn!
