Sizechart Helmets
Before you order a helmet, it is important to choose the right size. Wearing a helmet which is too large or too small, can adversely affect your safety. Please note that a new helmet might feel tight at the beginning.
You can use a tape measure to measure the circumference of your head. Place the tape measure about 2 cm above your eyebrows and put it around your head. The table below gives an indication between circumference and size.
