Flanders 2 High Neck Warmer Long-Sleeve Baselayer - Men’s

What Our Gearhead® Experts Are Saying:

"I pulled the Flanders 2 High Neck Warmer Long-Sleeve Baselayer out for a brutal January ride where temps hovered just above freezing the entire time. The integrated neck warmer sealed out the cold right where I needed it most, and the fit stayed close enough to layer cleanly under my jersey without bunching up once."

When the thermometer drops into the mid-twenties, and the road still needs riding, the Flanders 2 High Neck Warmer Long-Sleeve Baselayer from Castelli is the piece that makes it possible. Designed specifically for the coldest days of the cycling season, it wraps the torso and neck in warmth while staying slim enough to sit cleanly under a jersey or jacket without adding bulk where you do not want it. That integrated seamless neck warmer is the detail that earns its keep most, sealing the gap between collar and chin where cold air finds its way in fastest.

At 244 grams, this is Castelli's warmest base layer option, built to handle temperatures between 25 and 40 degrees Fahrenheit without slowing you down. The regular fit keeps it snug enough for effective moisture management while giving you enough room to move through a full pedal stroke comfortably. Layer it under your coldest weather kit, and the whole system works harder because of it.
