Arena Spiky III Backpack 35 - Compact Swim and Training Rucksack

Our review of the Arena Spiky III Backpack 35 finds it best suited for swimmers and athletes who need a compact, organized bag for training and travel; the single biggest reason to buy is its practical compartment layout that separates wet and dry items while remaining comfortable to carry. The pack feels purposeful rather than flashy: a roomy top-loading main compartment, three zip pockets and mesh side pockets mean quick access at the pool, while the padded breathable back panel and ergonomic shoulder straps keep it wearable through long commutes and multiple training sessions.

Key Features

• Multiple compartments: A large top-loading main compartment plus three additional zip pockets provide tidy separation for clothes, towels and smaller accessories.
• Wet/dry separation: Mesh inserts and a water-repellent bottom help control moisture and protect contents from wet floors after practice.
• Comfort-focused carry: Padded breathable back panel and ergonomic shoulder straps reduce strain on shoulders during travel or daily use.
• Travel convenience: An integrated trolley belt makes it easy to attach the backpack to rolling luggage for pool meets or trips.
• Bottle and quick-access storage: Mesh side pockets are sized for water bottles or items you need to reach without opening the main compartment.
• Durable construction: Reinforced bottom and robust zippers give a sense of build quality that users say holds up through a season of daily use.

Who It's For

The Arena Spiky III Backpack 35 is aimed at swimmers, triathletes and gym-goers aged 13 and up who need a mid-size bag for training sessions and local competitions. Its 35 liter capacity, compact 18 x 9 x 12 in footprint and multiple pockets make it ideal for carrying a towel, swimwear, goggles, fins and a change of clothes while keeping wet items separated.

It is less suitable for users who need a large expedition pack or weekend travel suitcase; those requiring heavy padding, laptop-safe compartments with dedicated sleeves, or much larger volume should look elsewhere.

Pros & Cons

Pros

• Well organized pockets and mesh compartments make kit management fast and efficient.
• Comfortable padded back panel and shoulder straps allow daily use without discomfort.
• Water-repellent bottom and mesh inserts help keep gear drier and protect items from wet floors.
• Sturdy build and reinforced bottom improve longevity for regular swim-season use.

Cons
