Description

The Castelli Flanders 2 long sleeve undershirt keeps you warm during the coldest rides.

The soft fleece fabric with stand-up collar keeps your body temperature stable, even in freezing temperatures.

Thanks to the breathable mesh inserts, you stay dry, even during high-intensity exercise.

Perfect as a base layer for winter training and long rides in low temperatures.

Please note: keep in mind that Castelli clothing runs smaller than normal.

The Castelli SottoZero base layer is designed for cyclists who won't let the cold stop them. This base layer is the ideal foundation for winter rides, offering exceptional warmth and comfort without compromising breathability. The SottoZero fleece fabric—made entirely from 100% polyester—feels soft against the skin and provides excellent insulation, while efficiently wicking away excess heat and moisture.

The stand-up collar protects your neck from cold air and prevents heat loss, keeping your core optimally warm. Strategically placed mesh inserts under the armpits maintain ventilation, even during intense rides. Flat Merrow stitching minimizes friction and prevents irritation, so you can keep moving comfortably, no matter how long your ride.

Whether you're training on a freezing cold morning or riding long winter miles, this base layer will keep your body dry, warm, and comfortable—exactly what you need to maintain your performance.
