How the Minato Premium Backpack Expansion Works
Minato Premium is designed to adapt to your day – whether you're going to work, the city, or a weekend getaway. Thanks to the smart expandable volume system, you can change the size of the backpack within seconds according to your current needs.
Three sizes, one backpack
- 20 L – Compact mode: Ideal for everyday carrying. The top part is rolled and secured with a Fidlock® magnetic buckle. The backpack is slim, elegant, and holds its shape well.
- 30 L – Medium mode: Just unroll the top part and fasten the buckles. You get more space for a sweatshirt, laptop, or gear for the whole day.
- 40 L – Fully expanded mode: The top part unfolds fully and the side compression straps are loosened. At that moment, you have a full-fledged backpack for the weekend or travel from a city backpack.
How to enlarge the backpack
- Unfasten the top Fidlock® magnetic buckles.
- Unroll the rolling part upwards – the fabric is soft and flexible, so it unfolds effortlessly.
- Loosen the side compression straps – this frees space for the full extension of the top part.
- Fill the backpack as needed – the construction and internal reinforcements ensure that even after expansion the shape remains stable.
- After filling, roll the top part again and secure the buckle in the new position.
In this simple way, Minato Premium adapts to your daily rhythm. Whether it's a regular day in the city or a weekend adventure, the backpack remains functional, organized, and stylish.
Technology and materials
Each Minato Premium backpack is handmade in the Czech Republic from CORDURA® 1000D material. This technical fabric is known for its high resistance to abrasion, water, and UV radiation. The C0 DWR surface treatment repels water without using harmful fluorocarbons.
Thanks to these technologies, the backpack stays dry even in rain, holds its shape when fully packed, and lasts much longer than ordinary backpacks made from common textiles.

Tip for everyday use
For city carrying, keep the backpack in 20 L mode – it will be light, elegant, and compact. When you know you have a longer day or trip ahead, expand it to 30 L. And for the weekend or travel, fully utilize its full capacity of 40 L.
Thanks to the smart system of buckles and zippers, the backpack adapts without deformation and maintains a stable shape in every configuration.
