I featured this backpack briefly in a post with other bags but thought it deserved one of its own.
Here is the description from the Kero website, translated from Swedish:
This rucksack has a thicker type of leather, with one outside- sewn pocket. Inner pocket inside rucksack. Carrying handle on top. Approximately 20l. Measures 33 x 30 x 18 cm. it’s made from naturally tanned leather crafted in Swedish Lapland above the Arctic Circle in Sattajärvi shoemaking. High quality, water-repellent leather and only with metal buckles or a lock made by horn, made in Sweden. 3 years warranty. Naturally-tanned reindeer hide. Kero specialty is the naturally tanned leather which means that the skin is tanned with only natural substances. This method is known since time immemorial and by far the most environmental friendly. Tanning agents from bark are added to the process, and the leather also takes on the moisture-absorbent properties of the bark.

They also make Swedish ‘duck boots’ – näbbstövlar or ‘näbbisar’. These have a slight frump stamp on them in Sweden but I love them to bits. Here are mine, bought a few years ago
