CastelliActive Cooling Sleeveless - Cycling technical base layers

Imagine yourself racing down mountain passes under a scorching sun, each pedal stroke bringing you closer to the finish line. But instead of letting the heat slow you down, your Active Cooling Sleeveless from Castelli provides an unparalleled cooling sensation. Designed for passionate cyclists, it uses an ingenious combination of hydrophilic and hydrophobic yarns to regulate moisture and maintain optimal body temperature.

The secret lies in its special open-knit construction, allowing air to circulate freely while retaining just the right amount of moisture against the skin. This process creates an evaporative cooling effect, keeping you cool as you give your best. Imagine a personal fan, but without the batteries! Ideal for days when the sun offers no respite, this base layer fits perfectly under the Climber's Jersey or the Superleggera, and also works wonders with any breathable jersey.

Put on the Active Cooling Sleeveless and let the technology do the work while you focus on conquering new heights. A smart choice for those who don't want to choose between performance and comfort, even in the most oppressive heat. So, ready to tackle the next climb with a powerful ally? Your next cycling adventure awaits!
