This is an accessory that came with the purchase of a helmet. I thought it was a helmet cover, but upon checking, it was a mask. I don't use this type of mask, so I took photos of it as is, making it an unused item. Color: Black Length: Approximately 40cm, Width: Approximately 23cm Unisex *Helmet is not included. Made of stretchy material that is easy to wear, comfortable, breathable, and has sweat-wicking and quick-drying properties, making it recommended for long periods of wear. Great for cycling, touring, winter sports, fishing, mountain climbing, and survival games! An essential item for outdoor activities in winter, allowing you to forget the cold and immerse yourself in your activity. It's a thin type, so it's not stuffy, and it's especially recommended for those who wear a helmet or hat over it.
