Castelli Flanders 2 High Neck Warmer Base Layer
When the temperature drops and your breath hangs in the air, the Castelli Flanders 2 High Neck Warmer Base Layer becomes an essential part of your winter cycling kit. Designed for deep winter riding, this is Castelli’s warmest synthetic base layer, made from SottoZero multi-denier 100% polyester fleece fabric. It delivers exceptional insulation and moisture-wicking, keeping your core warm and dry in freezing conditions. The built-in high neck warmer adds an extra layer of protection, doubling as a face mask or helmet liner to shield you from biting winds and icy air.
With thoughtful details like flat Merrow stitching to prevent chafing and a mesh armpit insert for improved breathability, the Flanders 2 Base Layer is crafted for comfort during high-effort rides in sub-zero temperatures. Designed for use between -4°C and 6°C, it pairs seamlessly under your winter jacket to create a defence against the harshest conditions.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
