The Black A4 Shoulder Bag

The black mobile office is back - and it's sturdier than ever!

Don't let the measures of this bag fool you. The A4 is the perfect mobile office, that'll let you establish a productive day, wherever you go. It can take most of the new compact laptops (13” and less), a good size water bottle, and even a slim lunchbox. Classic A4 size fits your essential papers even with a light folder.

Mind you that we've perfected the A4 and made it for our G-buckle. The G-buckle is lighter than the old stock L-buckle. If you are into the Kasperi signature L-buckle, the last chances to get it are on hand. The new A4 is also made from sturdy and time-tested german SOHRE tanneries leather, which we are really excited about.

Special Kasperi G-buckle makes the operation easy and secure and two extra pockets keep small things and modern smartphones organised.

FAQ

How should I care for my leather bag?

You can start using your bag straight out of the box. Leather works well even in bad weather conditions, and getting wet is fine as long as it is properly cared for. Of course the harder use, the faster patina, but that only ads character to the bag.

Treat with wax every 4-6 months or when the leather feels like it's drying, treat lightly with wax. Wipe the leather to clean it. With a cloth spread a thin layer of wax on the leather. Allow the wax to permeate overnight and then polish the remainders off with a cotton or wool cloth. The scent of tar will fade away in a couple of days, if a lot of wax is applied, this will take longer.

We recommend using natural products like bees wax based products or natural oils. Synthetic leather protection can block the pores of the leather. This will reduce the leather's ability to absorb wax and oils - ultimately reducing the lifespan of the bag

How long is the break in period of the leather bag?

We believe that leather is the best material for bag because it conforms to our bodies over time and can last for decades while remaining in good condition.

Like all high quality leather goods, Kasperi bags also have a break-in period. It will take a couple of weeks of active use for the shoulder straps to start forming to your body. If you experience any pressure points, squeeze the straps lightly with your hands from the pressure points to help it form faster.

Closing and opening the buckles is also stiff at first but as the leather loops softens and form over time it will become fluid.

With proper care and use, these bags develop a unique patina and become more personal by the day.

What about repairs or service?

We believe in the “right to repair”. Every aspect from structures to material thicknesses are considered for repairability. Because our bags are designed to last for decades, it is inevitable that they will require servicing at some point. The hardest wearing parts like the shoulder straps are made from 3 mm leather so that they will last for decades of use.

The hardest wearing parts (i.e. shoulder straps) are made from 3 mm leather for longevity and the whole structure is designed with serviceability in mind.
