Sorry other heritage brands, Filson might be the top dog on the market. If the brand's mainline offerings weren't strong enough to convince you, then its collaboration with Japan's Nanamica (Red Label) should do the trick. Normally, exclusive Japanese goods cost an arm-and-leg to ship (if you can even order from the website), but you're in luck:Need Supply Co. is expressly carrying two briefcases from the line.
We usually don't mess with briefcases, but these two can function as a bag and come in easy to use colors: red and blue. Save up $295, and it can be yours. Shop the collection here.
