The DERBY Flex-R convertible backpack with a capacity of 44–56 liters is a durable, comfortable, and highly versatile accessory for travel, sports, and daily use.
The model is made of practical, water-repellent OXFORD 300D fabric, which is highly resistant to wear and tearing. Reliable shoulder straps, sturdy hardware, and high-quality zippers ensure comfort and longevity even during intensive use.
The main advantage of this model is its smart three-level transformation system. When fully folded, the backpack turns into a miniature 20×20 cm pouch, which is convenient to keep on hand or pack into a suitcase or bag. When unfolded, it becomes a spacious backpack measuring 55×40×20 cm, perfectly meeting the carry-on luggage standards of most airlines. If necessary, the bottom of the backpack expands by an additional 15 cm in height, increasing the overall dimensions to 70×40×20 cm for maximum load capacity.
Thanks to its well-thought-out design, the backpack instantly adapts to your needs. It is ideal as your primary luggage, a convenient sports bag, or a "backup" backpack in case you make extra purchases during your trip.
