How we reviewed: We checked the manufacturer’s published specifications and current product listing details, then evaluated the design for common pool, gym, and meet-day needs. This is an editorial assessment, not a hands-on durability test.
Swim gear creates a packing problem: you need room for bulky training tools, but you also need to keep damp items away from dry clothes and small valuables. The ARENA Team 45 Backpack addresses that problem with a 45-liter top-loading design, separate wet-storage features, and several exterior pockets. Its strongest points are capacity and pool-focused organization, while its main tradeoff is size, especially when you fill it with fins, towels, shoes, and dry-land clothing. This review explains what the bag includes, how it works in daily use, and who should consider a smaller alternative.

What Is the ARENA Team 45 Backpack?
The ARENA Team 45 is a large training backpack made for swimmers and athletes who carry more than a suit, goggles, and towel. Its 45-liter main compartment gives you room for training gear, dry clothing, footwear, drinks, and smaller accessories without forcing everything into one open cavity.
The layout is built around moisture control. You get a separated waterproof compartment, a large mesh pocket for wet gear or shoes, side pockets, and an included swimbag. The padded breathable back panel and shoulder straps are designed to make a full load more manageable, although the bag’s size still matters when you are walking long distances or packing lightly.
Before You Buy: The reinforced bottom and separated compartment are described as waterproof, but the manufacturer does not describe the entire polyester backpack as fully waterproof. Do not treat it like a dry bag or leave electronics exposed during heavy rain.
Who Should Buy It?
Best For
- Competitive swimmers carrying fins, paddles, a pull buoy, towels, clothes, and recovery items.
- Athletes who move between pool training and dry-land workouts in one trip.
- Swim families who want a large, organized bag for meets and long practice days.
Skip If
- You carry only a swimsuit, goggles, sandals, and a small towel.
- You need a compact backpack for a smaller torso or crowded commute.
- You need guaranteed airline personal-item sizing or a confirmed padded laptop compartment.
Feature-by-Feature Review
Capacity and Main Compartment
The 45-liter capacity is the main reason to choose this backpack. The wide-mouth top zipper lets you see and reach bulky gear more easily than a narrow school-style opening. You can pack training tools at the bottom, place dry clothing above them, and keep quick-access items in the side pockets.
That space can also work against you. A large compartment makes it easy to overpack, and loosely packed small items may settle to the bottom. Packing cubes or small zip pouches can help you keep caps, goggles, anti-fog solution, keys, and toiletries from getting lost.
Wet and Dry Gear Separation
The bag provides several ways to isolate damp items. The separated waterproof compartment helps control moisture, the large mesh pocket can hold wet gear or shoes, and the included swimbag gives you another layer of separation after practice.
This setup is useful, but ventilation does not replace drying. Wet suits and towels can still create odor if you leave them sealed inside the backpack. Unpack the bag when you get home and let the damp compartments remain open until they are dry.
Side Pockets and Small-Item Storage
Two mesh side pockets can hold water bottles or damp items, while two zippered side pockets give you more secure storage for accessories. The badge-holder carabiner is useful for a team tag, credential, or lightweight accessory.
The organization is practical for swim gear, but it is not a technical travel organizer. The manufacturer identifies an inner pocket for separating dry clothes from wet training gear, not a dedicated padded electronics compartment. Check the exact seller variant before relying on it for a laptop.
Build Quality and Materials
The backpack uses 100% polyester, oversized YKK zippers, and a reinforced bottom designed to resist abrasion and protect the contents from wet pool-deck floors. These are sensible choices for a bag that may be placed on rough concrete, tile, bleachers, and damp locker-room surfaces.
The waterproof claim is limited to specific areas. The bottom and separated compartment provide water protection, but the outer shell should be treated as a durable sports-bag fabric rather than a submersible barrier.
Carrying Comfort
A padded breathable back panel and comfortable straps help distribute a training load and reduce heat against your back. The design should feel more supportive than an unstructured mesh sack when you carry dense gear.
Comfort still depends on packing. Heavy items placed far from your back can make the bag pull backward, and a fully loaded 45-liter pack may feel large on a shorter frame. Put the heaviest dry items close to the back panel and tighten both shoulder straps evenly.
Pro Tip: Use the included swimbag for the wettest items, then keep the mesh pocket for sandals or shoes. This gives you two separate damp zones and makes it easier to empty the backpack after practice.
How It Performs in Real Use
For Daily Pool Training
For a regular practice, the bag gives you enough room to separate a towel, dry clothes, goggles, cap, toiletries, and common training tools. The wide opening saves time when you are changing quickly, while the side pockets keep your drink and small items within reach.
For Swim Meets
Meet days often require extra towels, warm clothing, snacks, recovery items, and backup goggles. The 45-liter volume is useful in that setting, especially when you need to keep wet race gear away from dry layers between events. The tradeoff is a larger footprint beside crowded bleachers.
For Pool and Gym Sessions
The bag is a strong fit when one trip includes swimming and dry-land work. You can carry workout clothing and shoes along with swim equipment, then use the wet-storage areas after your session. Careful packing matters because shoes, a towel, and training tools can quickly make the load heavy.
For Travel
The rectangular 52 × 35 × 27 cm body can work as a gear-focused travel backpack, but it should not be assumed to meet every airline’s under-seat personal-item limit. Check your carrier’s current size rules before flying, and do not pack the wet compartment until it has dried fully.
How to Pack and Care for It
- Load heavy items close to your back. Put dense dry gear near the padded panel so the backpack does not pull away from your shoulders.
- Separate the wettest items. Place soaked swimwear in the included swimbag or waterproof compartment instead of mixing it with clothing.
- Use pouches for small accessories. Keep goggles, caps, clips, toiletries, and electronics together so they do not sink to the bottom.
- Empty it after practice. Remove damp items, wipe moisture from the bottom, and leave the compartments open to air-dry.
- Clean gently. Follow the care label. When needed, hand-clean soiled areas with mild soap and cool water, then air-dry the bag completely.
Pros and Cons
Pros
- Large 45-liter capacity for full swim and dry-land training loads.
- Multiple wet-storage options, including a separated compartment and included swimbag.
- Wide-mouth top opening makes bulky equipment easier to load and reach.
- YKK zippers and a reinforced abrasion-resistant bottom suit frequent pool use.
- Padded breathable back panel improves comfort compared with an unstructured gear sack.
Cons
- The 45-liter body may be bulky for light sessions or smaller users.
- The complete backpack is not confirmed as fully waterproof.
- A dedicated padded laptop sleeve is not clearly stated on the manufacturer’s product page.
Is It Worth the Price?
The ARENA Team 45 sits in the purpose-built swim-backpack category rather than the basic gym-bag category. Its value comes from the combination of 45-liter capacity, wet/dry organization, pool-deck protection, YKK zippers, and carrying comfort.
It is worth considering when you regularly fill a smaller bag or need one pack for pool and dry-land equipment. It offers less value when you carry a minimal kit, need a compact commuter bag, or want a clearly specified padded laptop section.
How It Compares to Alternatives
The Speedo Teamster 2.0 is a useful comparison when you want a smaller 35-liter swim backpack and a clearly identified laptop sleeve. The TYR Spirit Team Alliance 45L is closer in capacity and deserves a look if you want another full-size team bag. Within arena’s lineup, the Spiky III Backpack 45 is the most direct same-brand alternative.
The ARENA Team 45 makes the most sense when you value a wide top opening, several wet-gear options, and the included swimbag. A smaller alternative may be better when portability matters more than maximum capacity.
Frequently Asked Questions
Is the ARENA Team 45 Backpack fully waterproof?
No full-backpack waterproof rating is stated. The manufacturer describes the reinforced bottom and separated inner compartment as waterproof, so you should still protect electronics and other moisture-sensitive items.
How large is the backpack?
It holds 45 liters, or 2,746 cubic inches, and measures 52 × 35 × 27 cm. That is about 20.5 × 13.8 × 10.6 inches, which is large enough for a full training load but bulky for minimal gear.
Can it keep wet gear separate from dry clothes?
Yes. It includes a separated waterproof compartment, a large mesh wet-gear pocket, an inner separation pocket, and a removable swimbag. You should still unpack damp items after practice so moisture and odor do not build up.
Does it have a laptop sleeve?
The manufacturer’s Team Backpack 45 page identifies an inner pocket for separating dry and wet gear, but it does not clearly call it a padded laptop sleeve. Some seller descriptions may vary, so confirm the exact listing before buying it for electronics.
Is it suitable for younger swimmers?
The manufacturer does not state a minimum age on the product page. Because the backpack is 52 cm tall and holds 45 liters, check the swimmer’s torso size and expected load before choosing it for a child.
How should you clean the backpack?
Follow the sewn-in care label. For routine cleaning, remove loose dirt, hand-clean soiled areas with mild soap and cool water, and let every compartment air-dry fully before storage.
What is the warranty period?
A specific warranty term is not stated on the manufacturer’s product page reviewed for this article. Check the Amazon seller details and arena’s current customer-service policy before purchase, especially when buying from a third-party seller.
Can you customize the backpack?
Standard retail listings do not promise personal design customization. Some swim-team dealers advertise customization for solid-color team orders, so contact the dealer directly if you need a logo, name, or team treatment.
The Bottom Line
The ARENA Team 45 Backpack is a strong choice for swimmers who carry a full training setup and need several ways to separate wet and dry gear. Choose it for its 45-liter capacity, wide opening, YKK zippers, and reinforced bottom, but skip it when you need a compact pack, full-bag waterproofing, or a confirmed padded laptop sleeve.
