Castelli Estremo Thermal Winter Skully Women's Cycling Beanie

Castelli Estremo Thermal Winter Skully

When temperatures drop, keeping your head and ears warm can make a real difference to your comfort on the bike. The Castelli Estremo Thermal Winter Skully is designed specifically for cold-weather cycling, combining high warmth with a slim profile that sits comfortably underneath a helmet. 🔥

Its construction is designed to provide warmth where you need it most while allowing moisture vapour to escape, helping you stay comfortable throughout your ride. The result is a practical winter cycling accessory that adds protection from the cold without unnecessary bulk. 🧢

Polartec AirCore Protection

The front-facing surfaces use Polartec AirCore, a fabric designed to manage wind exposure while helping protect against the cold. This provides targeted protection where your head is most exposed during a winter ride. 💨

Warmth Where You Need It

The rear section uses a warmer fabric designed to provide additional comfort and warmth while still allowing sweat vapour to escape quickly. This balance helps the Skully remain comfortable during active riding rather than simply trapping heat and moisture. 🔥

Full Ear Coverage

The Estremo Thermal Winter Skully fully covers the ears, providing additional protection in cold conditions. The fabric is thick enough to deliver the required warmth while remaining compact enough for comfortable use underneath a cycling helmet. 👂⛑️

Low-Profile Design Under the Helmet

A winter cap needs to provide warmth without interfering with your helmet fit. Castelli has designed the Estremo Thermal Winter Skully to take up minimal space under the helmet, making it a practical choice for cold-weather road rides and training sessions. 🚴
