AARON
Uni Rolltop rucksack

The Uni Rolltop backpack from the AARON brand is a very versatile product that can be used for leisure, sports or even work. The product has a modern yet discreet design that goes with any outfit. The backpack is made from 100% recycled material and is therefore also very suitable for environmentally conscious customers. The product is water-repellent and can therefore be taken anywhere without hesitation. In addition to a practical cell phone compartment, the backpack also has a laptop compartment that is suitable for notebooks up to 14 inches. Another positive feature is the hidden back compartment, which can be opened with a zipper above the back padding. The back padding is breathable and guarantees a high level of comfort. The storage space of the backpack is very variable – depending on your needs, it is possible to store luggage with a volume of between 18 and 26 liters. The backpack can be adjusted to the exact size required thanks to its infinitely variable adjustment. Another positive aspect is that if the product does not meet the buyer’s expectations, the seller offers to refund the money for the purchase.

The roll-top backpack offers a high level of carrying comfort. The generous back padding and carrying straps allow the product to be comfortably strapped to the back. Thanks to the breathable mesh of the back padding, the rucksack is also perfect for active sports enthusiasts. The water-repellent surface of the backpack ensures that liquids run off – so the backpack can be used without hesitation even in rainy weather. In addition to the large main compartment, the rucksack has numerous other larger and smaller compartments for stowing a wide variety of items. The laptop compartment and other small compartments, which can be used to store a cell phone or keys, for example, are particularly noteworthy. Overall, the product offers plenty of storage space with a capacity of between 18 and 26 liters, which can be individually adjusted as required. There are slight deductions for the fact that there is no space on the outside of the rucksack to stow a drinks bottle. This would ensure sufficient space and better protection against liquids for the laptop inside. The light basic weight of the backpack avoids an unnecessarily heavy load. In terms of security, the security compartment on the back of the backpack is impressive. This makes it possible to stow valuables safely on the back. The simple yet modern design rounds off the product. This product is a high-quality backpack that fully fulfills its purpose and is also made from environmentally friendly materials.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.7 stars. In some cases, there are complaints that the front pockets are a little too small . On the other hand, the spaciousness, the water-repellent effect and the beautiful design are positively emphasized. In our practical test, we were able to confirm that the surface is water-repellent and we were also impressed by the spaciousness. Consumer criticism of the pockets being too small is partly justified, as the need for storage space in smaller pockets is very individual , e.g. due to the size of the smartphone.

Prices of up to €59.99 are charged on the Internet for equivalent products. Very affordable products are available from as little as €40 . The Uni Rolltop backpack from AARON is therefore currently in the middle price segment with a price of €49.99. For the quality and performance received, the price-performance ratio is very good.
