Back to Basics

KEP Italia helmets feature a polycarbonate and carbon fiber combination . Polycarbonate is a pliable material commonly used in eyeglasses , greenhouses , digital discs , etc . The impact strength of polycarbonate rates towards the top for impact strength , but can be susceptible to scratching .
The Inner Layer
The inner layer of the helmet provides comfort for the wearer — if you had to wear something rigid day in and day out , you most likely wouldn ’ t be compelled to wear it , right ? So helmet manufacturers may add a thin liner to the inside of the helmet for a softer feel , while also protecting the shock absorbing layer from the inside .
These inner layers can include a mesh comfort liner to help wick away the rider ’ s sweat , as well as some extra foam for the comfort and ability to make the fit a little more custom . One K ’ s Air helmet even includes inflatable air pockets in the liner , which allows for the riders to adjust the helmet for comfort and fit .
Retention Straps
No helmet is effective if the retention , or chin , straps do not exist . The retention system , often referred to as straps and buckle , keep the helmet on the rider ’ s head during a fall when fitted and used correctly .
Most retention straps are made from a nylon webbing and plastic buckle . Some may include soft fabric covers that can cover the underside , being held together with Velcro . Some , like Gatehouse , might also be made of suede or leather .
Passing The Test
Did you know that wearing a helmet could reduce the risk of riding-related head injury by an estimated 50 percent , as well as the risk of death due to head injury by a whopping 70-80 percent ? To ensure a helmet can accomplish these tasks , it must pass a series of tests . There are several different tests based on where you are located around the world . For instance , in the United States the standard is the ASTM / SEI ( American Society for Testing and Materials / Safety Equipment Institute ), which includes three main tests : the impact test , the side distortion test , and the penetration test . The impact test measures the helmet ’ s ability to absorb a blunt force impact should a rider fall on their head , say onto pavement while trail riding .
The side distortion test simulates what could happen if 1,200 pounds of horse happens to land on your head during a fall . It measures the ability of the helmet to resist distortion , should that scary accident happen to you .
The penetration test measures the resistance the helmet offers to a pointed object into the ventilation area . It uses an equestrian hazard anvil , designed to approximate the angle of a horseshoe or a jump standard edge , to ensure there is no penetration by a sharp object whilst wearing your helmet .
Other testing certifications include the PAS 015 ( British standard ), and the AS / NZS 3838 and ARB HS 2012 ( Australian standards ).
Time for a Change ?
It is recommended that all helmets be replaced after an impact , even if you don ’ t see much physical damage to the helmet with your naked eye . General wear and tear of a helmet not only shows its age perhaps on the outer layer , but the materials that soften the impact can degrade within three to five years .
“ Longevity depends on how frequently the hat is used , the conditions of use and how the helmet is stored and even transported ,” says Paul Varnsverry , Technical and Safety Product Advisor for Gatehouse Hats .
All manufacturers recommend equestrians check their helmets regularly for any obvious signs of wear to the lining and retention straps , any cracks in the structure of the middle layer and the outer layer , and finally the operation and security of the buckle .
“ Irrespective of any signs of deterioration , it is recommended to replace the helmet after five years because the protective capacity diminishes over time due to the ageing of materials ,” explains Silvia Fantoni with KEP Italia SRL .
Working Together
There is no single most important material , or part of a helmet because the manufacturers and safety experts believe these materials must work together to protect the rider .
The equestrian helmet covers more of a person ’ s head than does a bicycle helmet , fitting lower on the head , particularly at the back of the skull , and has protection distributed evenly around the head , rather than concentrated in the front and top , which is why careful attention is taken by the world ’ s top brands .
