adidas Protour 3.4 Backpack: Complete Guide, Features, Size and Review

The adidas Protour 3.4 backpack is designed for people who want a spacious sports backpack that can handle padel equipment, clothing, accessories and everyday essentials without becoming difficult to organize. With a listed capacity of 40 liters and dimensions of 32 × 50 × 23 cm, the backpack provides considerably more room than a basic daypack while retaining a conventional backpack design. adidas describes the main compartment as having a U-shaped zipper opening, while the design also includes two zippered side pockets, an adjustable elastic cord on the front and a padded rear compartment intended for a laptop or other delicate items.

For padel players, the appeal of the adidas Protour 3.4 backpack is not simply its size. A sports bag needs to make equipment easy to access while also giving smaller belongings their own storage areas. The Protour 3.4 combines a large central compartment with separate side storage and a padded rear section, creating a layout that can work for training sessions, matches, tournaments and general travel. Retail listings for the 2025 version also identify it as part of adidas’s padel collection and list its capacity at 40 liters.

What Is the adidas Protour 3.4 Backpack?

The adidas Protour 3.4 backpack is a high-capacity padel-oriented backpack from adidas. Rather than using the shape of a traditional suitcase-style sports bag, it provides the portability of a backpack while offering enough internal space for clothing and sports equipment. The official adidas product information describes it as a roomy padel backpack, with a large central compartment designed for larger belongings and a padded rear compartment for a laptop or other items that need additional protection.

The design is particularly useful for players who want to carry several types of equipment in one bag. The 40-liter capacity gives the main compartment substantial room, while the two zippered side pockets can be used to separate smaller personal belongings. The front elastic cord provides another useful feature because it can help adjust the external volume of the bag or hold lightweight items against the outside. Together, these elements make the Protour 3.4 more versatile than a simple backpack with one large compartment.

adidas Protour 3.4 Backpack Size and Capacity

One of the most important specifications to consider is the size. adidas lists the adidas Protour 3.4 backpack at 32 cm × 50 cm × 23 cm, with a total capacity of 40 liters. This gives the backpack enough space for sports clothing, towels, accessories and other equipment while still maintaining a backpack format that can be carried on the shoulders.

A 40-liter capacity can be particularly useful when you need to pack for a complete training session rather than simply carrying a racket. Players may want to bring a change of clothes, shoes, towel, water bottle, personal items and other accessories to the court. The larger capacity also makes the bag practical for people who want one backpack that can transition between sports and everyday activities. Because the actual amount you can carry depends on the shape and size of individual items, however, capacity should be considered alongside the compartment layout rather than as the only measurement.

Large U-Shaped Main Compartment

The main compartment is one of the defining features of the adidas Protour 3.4 backpack. adidas specifies a U-shaped zipper closure, which allows the opening to extend farther than a narrow conventional backpack opening. This can make it easier to see and reach items stored toward the bottom of the bag, especially when the backpack is packed with clothing or sports equipment.

A wide opening can also make packing more organized because you can arrange larger items without having to push everything through a small opening. For padel players, this is useful when preparing a bag before a match or training session. Instead of treating the backpack as a simple container, the large central compartment can be organized around the different items you expect to use during the day.

Two Zippered Side Pockets

Organization is another important part of the adidas Protour 3.4 backpack. The model includes two side pockets with zippers, giving users dedicated spaces for smaller belongings. adidas specifically identifies these pockets as useful for organizing personal items.

Separate zippered pockets can be useful for items such as keys, cards, small accessories or other belongings that you do not want buried underneath sports equipment. Keeping frequently accessed items away from the main compartment can also make the backpack easier to use when you are moving between home, transportation and the padel court.

Padded Rear Compartment for a Laptop

The backpack also includes a padded rear compartment. According to adidas, this compartment is intended for carrying and protecting a laptop. This feature expands the usefulness of the Protour 3.4 beyond sports because the bag can also accommodate technology and work-related equipment.

For someone who travels directly from work or school to a training session, this type of compartment can be especially convenient. Rather than needing a separate laptop bag and sports bag, the padded rear section provides a dedicated area for a computer or another delicate item. Users should still check the dimensions of their particular laptop against the compartment before relying on it for a specific device.

Adjustable Front Elastic Cord

The front of the adidas Protour 3.4 backpack features an adjustable elastic cord. adidas describes this feature as a way to adjust the volume of the backpack according to your needs. The cord also gives the backpack an additional external attachment area for suitable lightweight items.

This feature can be useful when the amount you carry changes throughout the day. A player may leave home with a relatively full bag but have fewer items later after changing clothes or removing equipment. The adjustable cord adds some flexibility to the exterior design without requiring another large compartment.

Comfort and Carrying Design

A backpack’s capacity is only useful if it can be carried comfortably. The adidas Protour 3.4 includes padded mesh shoulder straps and a padded mesh back panel, features that adidas identifies as part of its comfort-focused construction. The mesh material is also consistent with the backpack’s sports-oriented design.

For people who regularly walk to a sports facility, travel by public transportation or carry their bag for extended periods, shoulder straps and back padding can make a noticeable difference. Proper adjustment is still important, because even a well-padded backpack can feel uncomfortable if it is overloaded or positioned incorrectly. Distributing heavier items close to the back can also help make a full 40-liter backpack feel more balanced.

Materials Used in the adidas Protour 3.4 Backpack

The official adidas listing identifies the backpack as being made with polyethersulfone and recycled polyester. Retail listings for the 2025 version similarly describe the construction as using these materials and emphasize the use of recycled polyester.

Material selection matters because a sports backpack is likely to experience repeated handling, transportation and loading. The Protour 3.4 is designed for regular sports use while maintaining a relatively polished adidas appearance that can work outside the court as well. Buyers should nevertheless remember that material construction does not mean the backpack is automatically waterproof, so the manufacturer’s care and weather-resistance guidance should be checked before using it in heavy rain.

adidas Protour 3.4 Backpack for Padel

The adidas Protour 3.4 backpack is particularly relevant to padel players because it provides space for sports equipment without requiring a traditional oversized gear bag. Its 40-liter capacity, large central opening and additional storage areas make it suitable for carrying the collection of items commonly needed for a training session or match.

For a typical padel day, the main compartment can accommodate clothing and other larger items, while the side pockets can be used for smaller personal belongings. The padded rear compartment adds another layer of versatility for players who travel with a laptop. This combination means the bag can function as a sports backpack while still fitting into a broader daily routine.

adidas Protour 3.4 Backpack for Everyday Use

Although the backpack is associated with padel, its design is not limited to sports. The 40-liter capacity, laptop compartment, side pockets and comfortable shoulder straps can make it useful for commuting, short trips, gym sessions or other activities where a large backpack is convenient. adidas itself describes the padded rear compartment as suitable for a laptop, which supports its crossover between sports and everyday use.

The main consideration for everyday users is whether they actually need 40 liters of storage. A large backpack can be extremely useful for people who carry clothing, technology and accessories, but it may feel larger than necessary for someone who only needs a laptop and a few personal items. The Protour 3.4 therefore makes the most sense for users who regularly need substantial storage capacity.

How to Organize the adidas Protour 3.4 Backpack

The easiest way to get the most from the adidas Protour 3.4 backpack is to assign different categories of belongings to different parts of the bag. Larger and softer items such as clothing and towels can go into the central compartment, while small personal items can be placed inside the zippered side pockets. A laptop or another delicate item can be placed in the padded rear compartment, provided its dimensions are appropriate.

The front elastic cord can be useful for lightweight items that you want to keep accessible, although anything placed externally should be secured properly. Organizing the backpack this way reduces the need to search through the main compartment every time you need a small accessory. It also helps distribute the contents more evenly, which can improve carrying comfort.

adidas Protour 3.4 Backpack: Important Specifications

Here are the key specifications currently listed for the model:

These specifications are based primarily on adidas’s product listing, with supporting details from current retailer listings.

What Makes the adidas Protour 3.4 Backpack Different?

The main distinction of the adidas Protour 3.4 backpack is the combination of a relatively large 40-liter capacity with a backpack-oriented carrying system. Instead of focusing only on racket storage, the design provides a broad central compartment, smaller organizational pockets and a padded laptop section. That makes it possible to use the same bag for sports and other daily activities.

Another notable aspect is the U-shaped opening. A backpack can technically have a large capacity but still be frustrating to use if its opening is narrow. The U-shaped zipper is intended to improve access to the central compartment, which can be helpful when the bag is packed with multiple layers of clothing or sports equipment.

Things to Consider Before Buying

Before buying the adidas Protour 3.4 backpack, consider how much equipment you normally carry. The 40-liter capacity is useful for players and commuters who need plenty of room, but a smaller backpack may be more appropriate if you usually carry only a few items. You should also check the current dimensions and color options from the retailer where you intend to purchase because product availability and regional listings can change.

It is also worth checking the exact version carefully. Some retailer descriptions of Protour 3.4 variants contain additional features that are not consistently listed across sources. For example, adidas’s official listing for the Black 3.4 clearly identifies the 40-liter capacity, U-shaped central zipper, two side pockets, front elastic cord and padded rear compartment. Comparing the specific product code and retailer description can therefore help avoid confusion between related Protour models.

Conclusion

The adidas Protour 3.4 backpack is a spacious and versatile option for people who need more than a basic daypack. Its 40-liter capacity, U-shaped main opening, two zippered side pockets, padded laptop compartment, adjustable front elastic cord and padded mesh carrying system give it a practical combination of storage and portability.

For padel players, the backpack provides enough room to organize clothing, equipment and personal belongings for training or match days. For everyday users, the laptop compartment and substantial capacity make it capable of working as a multipurpose backpack as well. The most important consideration is whether its relatively large 40-liter format matches your needs. If you regularly carry sports equipment, clothing and technology together, the Protour 3.4’s layout is designed around exactly that kind of use.
