Castle Slim Backpack

• Castle Slim gives you the polished look of a leather work backpack without the usual bulk. Its 7 cm profile stays close to your back, while separate compartments keep your daily tech and essentials organized.
• It's a good fit for commuting, meetings and days when you need more than a briefcase but don't want to carry a large backpack.

The Castle Slim takes the clean, structured character of our original Castle and pares it down for everyday carry.

At just 7 cm deep, its streamlined profile sits closer to your back and carries your daily essentials without the bulk of a traditional leather backpack. Multiple compartments keep your laptop, documents, cables and smaller items organized, while the zippered front pocket gives you quick access to the things you reach for most.

The padded back panel and adjustable leather-and-fabric shoulder straps make it comfortable for commuting, workdays and travel. Finished with metal hardware and crafted from premium leather, Castle Slim develops more character as you use it.

Leather is a natural material. Minor color changes and discrepancies on its surface are not quality defects. They are part of the nature of the genuine leather products.

Over time, your leather item will take on a warmer, softer look and get a unique patina. To keep your leather looking better, you can clean it occasionally with a clean white cloth and a neutral, natural leather-care cream.

Note about MagSafe Charging: When you regularly use MagSafe chargers and accessories in conjunction with the genuine leather cases, you might observe the emergence of a ring on your case. This is entirely normal, and you can minimize its visibility by applying a leather conditioner.
