One Go Backpack 45L
Stay organised and ready for every session with the arena One Go Backpack 45L. Its top-loading design makes packing effortless, while the spacious main compartment and four front zip pockets give you plenty of storage options.
Breathable, watertight inserts keep wet and dry gear separate. Inside, you’ll find a dedicated laptop sleeve, plus two external bottle pockets for easy access. Featuring Aquabreathe—arena’s advanced wet-management system—the backpack combines breathable and water-repellent fabrics to keep moisture out and your gear dry.
A breathable back panel ensures comfortable, sweat-free carrying. A practical luggage belt allows easy attachment to a suitcase, and an included carabiner lets you hang the bag conveniently. The water-repellent base and main fabric provide extra protection from dirt and damp surfaces.
