X-Bionic Performance Beanie X Black/Grey

Thermosyphon
Sweat management technology uses channels to enhance the body's natural thermodynamics. Maintaining a constant temperature of 37°C, it cools you when you sweat and warms you when you're cold, allowing you to conserve energy reserves and focus solely on your performance.

3D Bionic Sphere System
System that captures moisture before it becomes uncomfortable, blocking the sensation of overheating during intense activity and preventing cooling during rest and recovery phases.

Sweat Traps
Ergonomically positioned based on rigorous laboratory tests, the evaporation zones prevent the formation of sweat beads, providing constant active cooling.

Insulation Zones
Zones with differentiated textures, strategically positioned to ensure optimal management of body temperature.
