Tretorn are a Swedish company from the picturesque zone of Helsingborg.

Not only were they amongst the first people to make rubber-soled tennis shoes, but they’ve also been making ultra-nifty waterproof jackets since the 1930s.

Nearly a century later, they’re still dedicated to the outerwear cause, making high-class raincoats from eco-friendly materials (like sugar beet and fishing nets).

Very clever stuff.
