Luxury accessory maker Santiago Gonzalez has gone all out with this Crocodile Backpack, constructed of 100% Columbian crocodile leather. The street-ready pack has a capacity of 19 liters and the leather is designed to look better with a bit of wear – although at just under £4,820 a pop, I’m not sure how much wear and tear I’d be willing to give it. You can find one at Mr. Porter.
