Our little big JAGUAR is a great option for the winter season. Brim of the hat: 8.5 cm. Cup height: 13 cm. Material: Suede textile. SIZE GUIDE MEASURE YOUR HEAD Size S: 50 to 53 cm Size M: from 54 to 56 cm Size L: from 57 to 58 cm Size XL: from 58 to 60 cm You can use a tape measure (or a thread that you will have to compare to the side of a meter) to determine the length. Place the thread or tape around your head, above the ear. Hold the tape firmly, but not too tightly. Basically, you need to measure your head exactly where your hat is going to be. It is important that you feel comfortable. If you hesitate between two sizes, choose the larger size.
