15 liters : a cardigan, a book, a water bottle and the day's essentials. Inside, a large compartment with zippered and slip pockets keeps things sorted. Outside, the front slip pocket and two side pockets take what you reach for often, and the small zippered pocket on the back keeps valuables against your spine.

The material is water-resistant, not waterproof. It can withstand light rain and splashes, but avoid heavy or prolonged rain and immersion. Protect electronics separately, wipe off moisture and let the bag dry naturally away from direct heat.

The adjustable leather straps settle the bag to your build, and the reinforced leather handle takes over when you would rather carry it by hand. If you want a rucksack that also converts into a shoulder bag, its sibling the EVOA ladies leather rucksack does exactly that with removable straps.

That is how many women use it. The minimalist vintage cut reads as an accessory rather than luggage, and the zippered back pocket keeps wallet and phone out of reach of anyone but you, which matters on public transport.

Gram counters and technical hikers. Full-grain leather weighs 1.5 kg before you pack anything, and leather straps carry like leather, not like a padded harness. If you want the rucksack look in a lighter modern build, our Sandqvist backpacks are worth a look.

Almost nothing is needed. A cloth with a drop of vegetable oil erases light scratches; the marks that remain are the story of where the bag has been. Dry it whenever it gets wet and keep it away from light coloured fabrics: oil immersed leather can transfer a little colour, and if it does, it comes out in the wash.
