This is an inner cap to be worn under a bicycle helmet, such as for a road bike. The color is black and it's a free size. Inner caps are useful year-round, absorbing sweat in the summer to prevent it from getting in your eyes, and providing warmth in the winter. They also improve the fit of the helmet and keep the inside of the helmet clean, making them a great item. I received this as a gift, but I don't think cycle caps suit me, so I'm selling it. It's a new, unused item. ● Size: Free size. Please refer to image 4 for details. ● Material: Polyester ● Condition: New, unused ● Other notes: Stored in a home apartment. Please check the photos for details such as the design. ★ December 29th: Although I wasn't planning on lowering the price any further, I've lowered it for the sixth time for an early sale.
