Sport Direct "No Bounds BMX/Skate Bike Helmet Green 55-58cm CE EN 1078:2012

FOR GOOD MEASURE: To avoid disappointment let’s try to get this right and measure your head so you can select the correct size of helmet for you! Find a fabric tape measure and either a mirror or ask someone to give you a helping hand. Wrap the tape measure around your head above your eyebrows and about 1.5 cm above your ears. Make sure it goes around the largest part of the back of your head too. This will give you the circumference of your head in cm. If you don't have a fabric tape measure handy, wrap a piece of string around the widest part of your head and mark where it overlaps. You can then easily measure the length of the string using a ruler or a metal tape measure. HELMET SIZE: 55-58cm VENTILATION: There are an amazing 15 air vents for maximum cooling (including 4 rear) MATERIAL: Its out-mould construction fuses the polycarbonate outer shell with the helmets absorbing EPS foam inner core, giving you an exceptionally lightweight and strong helmet FULLY ADJUSTING SYSTEMS: Sport Direct BMX/Skate/Bike/Scooter helmets have fully adjustable unisize headlock systems and multi adjusting buckles for maximum ergonomic comfort, quick attachment and releasing.
