The Castelli Pro Thermal 3 Beanie featured here at Escapa is a thermal cycling beanie designed to protect your head during rides in cold weather. Its Thermoflex fabric combines warmth, stretch, and breathability in a thin garment that can be worn comfortably under a helmet.
With a claimed weight of just 39 grams, it provides insulation without adding excessive bulk or significantly affecting your helmet fit. Its one-size-fits-all design and regular fit make it a practical accessory for training and rides on road, Gravel, or Urban streets during the winter.
Warm and Stretchy Thermoflex Fabric
The Thermoflex fabric provides a soft, flexible surface that comfortably conforms to the head. Its construction helps retain body heat while allowing some of the moisture generated during exercise to escape.
The material’s stretch keeps the beanie securely in place during your ride and makes it easy to wear under different types of helmets.
Designed to be worn under a helmet
Its slim profile allows the Pro Thermal 3 Skully to be worn as a thermal layer under a cycling helmet. The snug construction minimizes wrinkles and prevents unnecessary bulk between the head and the helmet’s adjustment system.
Before starting your ride, be sure to check that your helmet maintains a secure fit and that the straps are properly positioned.
Flat seams for greater comfort
Flat seams help reduce pressure points and potential chafing during prolonged use. This feature is especially important when the beanie is compressed between the head and the helmet.
Rear reflective detail
The cap features a reflective detail on the back that improves visibility when illuminated by other vehicles. This element provides an added safety measure during rides at dawn, dusk, or in low-light conditions.
