Castelli Pro Thermal Women's Skully Mineral Red

Designed to keep you warm, this simple helmet liner features excellent moisture - wicking ability while minimizing bulk under your helmet. The Thermoflex fabric, which is warm, soft, and stretchy, effectively wicks away moisture. It has a raw - cut edge that lies flat and won't bunch under the helmet, so it doesn't interfere with the straps or helmet cage. There's also an opening at the back for ponytails. Weighing only 33 grams, it's a lightweight choice for women cyclists.

To use this Castelli thermal skull cap, simply put it on your head before wearing your helmet. Make sure the ponytail opening is at the back if you have long hair. When wearing the helmet, the cap should fit smoothly under it without getting in the way of the straps. For cleaning, it's best to follow the care instructions on the label. Usually, a gentle machine wash with cold water is fine. Avoid using harsh detergents or bleach as they may damage the fabric. After washing, let it air - dry to maintain its shape and quality. Don't expose it to direct sunlight for too long as it might fade the mineral red color. And always check for any signs of wear and tear regularly, and replace it if necessary.
