Helmet Safety and Replacement: What a Returning Rider Needs to Know
You rode as a teenager in whatever helmet the barn handed you. Coming back, the standards have moved, and the helmet is the one piece of equipment where the details are not open to preference. Here is what a certification means, what MIPS adds, and when a helmet quietly stops protecting you. This is the reference the rest of our helmet writing works from.
The standards to look for
In the United States, ASTM F1163 verified independently by the Safety Equipment Institute, or SEI, is the certification most riders will see. A helmet carrying the SEI mark has passed impact attenuation and retention testing under extremes of cold, heat and moisture. It is not the only route, and that surprises most returning riders.
USEF accepts four: ASTM F1163 certified through SEI, PAS 015:2011 certified through BSI or IC, VG1 01.040 2014-12 certified through BSI or IC, and Snell. USPC accepts six: those four, plus EN 1384 with a BSI Kitemark or IC mark, and AS/NZS 3838 with the SAI Global mark. A helmet carrying none of them does not belong on your head, whatever it costs.
The marks are frequently confused with one another. EN 1384 is the European equestrian standard. VG1 01.040 2014-12 is a separate interim standard, not another name for EN 1384. PAS 015:2011 is a further British standard. A helmet may carry several of them at once. Read the label inside the helmet as a list rather than looking for one particular mark, and check that at least one accepted standard actually appears on it. Then confirm the current requirement for your division in the rulebook of the organization sanctioning your competition, because a helmet accepted by one body is not automatically accepted by another.
What MIPS adds, and what it does not
MIPS, the Multi-Directional Impact Protection System, is a technology rather than a certification. A helmet fitted with it contains a low-friction layer that allows the shell to move against the head during an angled impact, redirecting some of the rotational energy. It complements a certified helmet. It does not replace certification, and no standard requires it. If you are buying new, it is a reasonable feature to prioritize.
The rule most returning riders miss: replacement
This is the rule that catches riders who have been away, because it applies to a helmet you already own and are otherwise happy with. A helmet has a service life, and that service life ends in one of two ways.
The first is a fall. Replace the helmet after any fall in which your head makes contact with the ground, a fence, a horse or anything else, regardless of whether you can see damage. This is not a cautious rule of thumb. The protective liner works by crushing, absorbing energy as the foam compresses, and once compressed it does not recover. A helmet that has taken a single impact has spent that capacity where it was struck and will not do the same job again. The damage is internal and often invisible, because the outer shell is designed to spread load and can look untouched over a liner that has already done its work.
The rule holds even when the fall felt minor, even when you remounted and finished the lesson, and even when the helmet looks perfect. It also holds for impacts off the horse: a helmet dropped hard onto concrete has taken an impact too. Check what the maker says in the documentation supplied with the helmet, and whether it operates a replacement program for helmets involved in a fall.
The second is time. Replace the helmet on the manufacturer's stated replacement schedule, which is published in the manual and often printed on a label inside the shell along with the date of manufacture. The interval is set by the maker rather than by a single universal rule, so read yours rather than assuming a figure quoted at the barn. The reason is that materials age. Foam, shell and harness degrade with heat, perspiration, ultraviolet exposure and time, and a helmet stored through summers in a hot car ages faster than the label anticipates. A helmet from your junior years is past that schedule several times over. However sentimental it is, it is not a helmet anymore.
Two points follow. Do not buy a used helmet, because you cannot know its fall history or its age. And check the date of manufacture on the helmet you do buy, since the clock runs from a date the maker sets rather than from the day it reaches you.
A final word on fit
A certified helmet only protects a head it is correctly fitted to. It should sit level, low on the forehead, and stay in place when you shake your head with the harness undone. Certification first, then fit, then everything else.
Certified helmets are in The Protected Rider, and each product page names the certification that helmet holds.
