The Flanders 2 High Neck Warmer Long-Sleeve Baselayer keeps you moving when temps drop
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.

Frequently Asked Questions
How should the Castelli Flanders 2 High Neck Warmer fit under cycling layers?
Castelli lists this men’s baselayer as regular fit, with a close feel suited to moisture transfer beneath a jersey and jacket. Use the product-page size chart to choose your fit, especially if you’re between sizes or comparing it with women’s sizing.When is the Castelli Flanders 2 High Neck Warmer best for riding?
It’s designed for cold-weather, high-output rides, with a listed temperature range of -4°C to 6°C (24°F to 42°F). Wear it beneath a cycling jersey and a protective jacket in exposed or wet conditions; it isn’t a standalone weather layer.How does the Flanders 2 High Neck Warmer compare with a lighter cycling baselayer?
Castelli describes it as the warmest synthetic-fleece baselayer in its range, making it a strong choice when extra insulation and neck coverage matter more than a lightweight feel. Its integrated neck warmer can also be pulled up for additional face coverage or worn under a helmet.How do you set up the Flanders 2 High Neck Warmer for a winter ride?
Pull it on as your next-to-skin layer, then add a jersey and jacket suited to the conditions. Position the integrated neck warmer around your neck, pull it over your face when useful, or wear it beneath your helmet as a liner.How should you care for the Castelli Flanders 2 High Neck Warmer?
Follow the garment’s sewn-in care label, avoid fabric softener and high heat, and air-dry when practical. Store it clean and fully dry; it’s a fleece baselayer, so reproofing isn’t needed.
