ADV Flex Backpack Dune Tennis Backpack
The ADV Flex Backpack Dune is a compact tennis backpack designed for players who want to take everything they need to the court but don't want to carry a large bag. It combines space for 2 tennis rackets, an extensive organization system, a protected laptop pocket, and expandable space for shoes or extra clothing.
With a standard capacity of 27 liters, it maintains a sleek, urban form, and when you need more space, the Expandable Gear Canopy system allows you to increase the backpack's carrying capacity to approximately 32 liters. This model is designed as much for the court as for daily commutes, work, or short trips.
Dedicated space for 2 rackets
Rackets are transported in a padded, thermally protected compartment that separates them from other equipment. The design helps reduce the impact of temperature and daily bumps and scrapes on the transported gear.
The Flex Backpack holds up to 2 tennis rackets, making it ideal for training or a match when you don't need a full tournament set of several frames.
Expandable Gear Canopy – extra space when you need it
One of the most distinctive features of the Flex Backpack is the expandable external Gear Canopy space. It allows you to attach larger items to the backpack without taking up space in the main compartment.
You can use it for tennis shoes, a sweatshirt, a jacket, an extra layer of clothing, or even a bicycle helmet. When additional space is not needed, the system remains folded and does not unnecessarily increase the backpack's size.
18 compartments – organized without fuss
Despite its compact dimensions, the ADV Flex Backpack offers as many as 18 different spaces and compartments. This means your phone, wallet, keys, overgrips, dampeners, glasses, cosmetics, and other small accessories don't have to end up in one large pocket.
The backpack also features quick-access pockets, allowing you to reach for the most needed items without opening the main compartment.
Full opening of the main compartment
The Flex Backpack can be widely unzipped, making access to the entire interior much more convenient than with a typical top-loading backpack.
This facilitates both packing before training and finding specific items without having to remove half the contents.
Secure laptop compartment
The dedicated computer pocket is secured with a waterproof zipper and a false bottom construction. This means the laptop does not rest directly on the bottom of the backpack, providing additional protection when placed on the ground.
This makes the Flex Backpack perfect for those who go directly to the court from work or university, or who take electronic equipment with them while traveling.
Separate space for cosmetics and small accessories
Inside, there is also a transparent pocket for cosmetics and small accessories. It allows you to quickly check its contents and separate items such as sunscreen, cosmetics, or hygiene products from electronics and clothing.
An additional hidden pocket in the back of the backpack provides a more discreet place for your phone, documents, wallet, or other valuables.
Hang the backpack by the court
At the top, there is a durable, hidden hook that allows you to hang the backpack on the court fence. This means it doesn't have to lie on the ground, and its contents remain conveniently accessible during a match or training.
Compact format for the court and city
The Flex is smaller than the ADV Tennis Backpack V2. It has a capacity of 27 liters, which can be increased to approximately 32 liters using the expandable Gear Canopy system.
With dimensions of approximately 45.7 × 30.5 × 19 cm, it maintains a compact silhouette and works well as both a sports backpack and everyday city or travel bag.
Materials prepared for daily use
The external construction is designed to protect equipment from daily use and changing weather conditions. The weather-resistant coating helps secure the contents, and the reinforced base allows the backpack to stand stably.
The whole is complemented by high-quality YKK zippers and a solid, stitched construction characteristic of ADV bags.

Less bulk, without sacrificing organization
The ADV Flex Backpack Dune is an option for players who want to maintain the characteristic ADV equipment organization but don't need a large backpack for three rackets and a full tournament kit.
Two rackets, a laptop, accessories, clothes, and shoes can be carried in one compact backpack that works well both on the court and for daily commutes.
The bright, subdued Dune color scheme gives the model a more elegant and lifestyle character, making the backpack look natural both on the court and in the city or while traveling.
The biggest advantage of the Flex is its flexibility: compact when you only need basic equipment, and more spacious when you really need extra room.
