About Arena ARC9400 Racing Swimming Silicone Cap (Aqua Force 3D)

The most advantageous hydrodynamic upgrade a swimmer can make is in their race cap of choice. The arena 3D racing cap family is moulded to provide a no-wrinkle fit optimising the hydrodynamics of your head. We aren’t saying that a cap is the only option, but outside of pushing your training limits in the pool it’s the easiest way to gain a hydrodynamic advantage.

The arena 3D Soft cap is revolutionising the racing cap mould by delivering a more comfortable fitting cap. Easier to put on, increased flexibility and superior comfortable, as hydrodynamic as our 3D Ultra Race cap.
