Tough times don’t last. Tough teams do.

Introducing the arena Diamonds collection, together we shine brighter.

Feel The Power – The Carbon Core FX is our most compressive race suit, with a locked-in feel and strong all over compression.

If you liked the Carbon Flex and Carbon Flex VX, you will love the Carbon Core FX. Offering a tight feel and exceptional core support. Increased lining provides more compression while double-taping down the back offers better body position.

The Carbon Core FX is the race suit of choice for Sarah Sjöström.

Discover the new arena Diamonds Collection

Since its inception in 1973, the arena logo has been composed of three diamonds, the strongest, most resilient gem on earth. The word diamond derives from the Greek “adamas”, which means invincible, and in popular tradition, three diamonds together represent the past, present and future. Drawing inspiration from these origins, the collection symbolises the strength of the human spirit, the power to overcome difficult times, to be present in the moment, and to shine on in the future.
