There is a specific kind of silence that only exists at the top of a mountain just before your first run of the day. As skiers, we live for that moment—the crisp air, the vast white horizon, and the promise of adrenaline. We invest in the fastest waxes, the sharpest edges, and the most breathable GORE-TEX shells. But often, the most critical piece of equipment we own is the one we think about the least: our helmet.
In recent years, you may have noticed a small, circular yellow sticker on the back of the most premium helmets in the shop. It simply says "MIPS." You might have also noticed that these helmets carry a higher price tag than their counterparts. This has led to a recurring debate on chairlifts and in ski lodges around the world: Is MIPS just a clever marketing gimmick designed to upcharge skiers, or is it a genuine life-saving advancement in alpine safety?
At Reanson, we have dedicated ourselves to the science of head protection. We understand that while the thrill of speed is what draws us to the slopes, our brains are our most fragile and irreplaceable assets. In this guide, we are going to peel back the layers—literally—to explore the technology behind MIPS. Our goal is to provide a sincere, technical, and transparent analysis to help you decide if that extra investment is truly worth it for your safety.
To understand why MIPS is significant, we first have to understand what it actually is. MIPS stands for Multi-directional Impact Protection System, a technology designed to reduce the rotational motion transferred to the brain during an angled impact.
The human body is remarkably resilient. Our brains are already protected by a natural "slip-plane" system: the cerebrospinal fluid. This fluid allows the brain to slide slightly inside the skull during an impact, providing a natural buffer. MIPS was developed by Swedish neurosurgeons and researchers who wanted to mimic this biological defense mechanism inside a helmet.
A MIPS-equipped helmet consists of three main components:
The EPS Liner: The standard foam interior that absorbs linear (straight-on) force.
The Low-Friction Layer: The signature "yellow plastic" liner.
The Elastomeric Attachment System: Small, flexible bands that connect the yellow liner to the foam.
When you fall, the MIPS layer is designed to move independently of the helmet shell by just 10 to 15 millimeters. While that might sound like a tiny distance, in the micro-seconds of a high-speed crash, that movement is enough to change the trajectory of the energy hitting your head.
For decades, helmet safety was measured by "linear" impact testing. This involves dropping a helmet straight down onto a flat surface to see how well the foam prevents the skull from cracking. While this is important, it doesn't reflect how skiers actually fall.
Skiers rarely fall in a perfectly straight line. Most alpine accidents occur at an angle—you catch an edge, your skis wash out, and your head hits the snow while your body is still moving forward. This creates rotational motion, which causes the brain to twist or slide inside the skull.
Traditional helmets are highly effective at preventing skull fractures caused by linear force, but they are often less effective at managing the rotational forces that lead to concussions and traumatic brain injuries (TBI).
By allowing the helmet to slide relative to the head, MIPS redirects that rotational energy. Instead of that energy being absorbed by your brain tissue, it is absorbed by the movement of the MIPS liner.
When browsing Reanson’s collection or any high-end ski shop, you’ll find that MIPS helmets typically cost between $20 and $50 more than non-MIPS versions of the same model. To determine if this is worth it, we have to look at the "Safety ROI" (Return on Investment).
Feature | Non-MIPS Ski Helmet | MIPS-Equipped Ski Helmet |
Primary Protection | Linear Impacts (Straight-on) | Linear + Rotational Impacts |
Average Price Range | $60 - $150 | $110 - $250+ |
Safety Certification | ASTM F2040 / CE EN1077 | ASTM F2040 / CE EN1077 + MIPS |
Concussion Risk Reduction | Standard | High (Significant reduction in strain) |
Weight Increase | 0g (Baseline) | ~20g to 45g (Negligible) |
Think of MIPS as a premium on your health insurance. A single visit to the emergency room for a concussion or a TBI can cost thousands of dollars in scans, therapy, and lost work time. Spending an additional $30 today to significantly reduce the risk of a brain injury that could affect your quality of life for years is, from a professional safety standpoint, one of the most cost-effective investments a skier can make.
We know that skiers are practical people. You want gear that works without being a nuisance. Here are the seven most frequent questions we receive at Reanson regarding MIPS technology.
Many users worry that the extra layer will make the helmet feel tighter or "weird" on their head. In a well-engineered helmet like those from Reanson, the MIPS layer is integrated so seamlessly that you should not feel any difference in fit compared to a standard helmet. The layer is paper-thin and sits between the padding and the foam, meaning your head still rests against the soft comfort liners you're used to.
Early versions of MIPS added a small amount of weight, but modern iterations (like MIPS Evolve or MIPS Air) are incredibly light. A MIPS system typically adds less than 45 grams to the total weight of the helmet—roughly the weight of a single AA battery—making it virtually undetectable to the wearer.
Because MIPS is a plastic layer, there was a concern that it would block the air holes in the EPS foam. However, Reanson engineers use "cut-out" MIPS designs that align perfectly with the helmet’s internal channels, ensuring that heat dissipation and airflow remain uncompromised.
This is a common misconception. You don’t need to be going 50 mph to suffer a concussion. A "slow" fall on a patch of blue ice can generate significant rotational force if you catch an edge. Because beginners are statistically more likely to have unpredictable falls or "catch edges," MIPS is arguably just as important for novices as it is for experts.
No. MIPS is not an after-market add-on; it must be built into the helmet during the manufacturing process to ensure the elastomeric attachments and the shell are calibrated to work together. Never attempt to "DIY" a safety system into your gear.
The yellow MIPS liner is made of high-durability polycarbonate and is designed to last as long as the helmet itself. As long as you follow the 5-year replacement rule and replace your helmet after any significant impact, the MIPS system will remain functional.
The data says otherwise. Independent testing labs, such as the Virginia Tech Helmet Ratings, consistently show that helmets equipped with MIPS (or similar rotational tech) outperform traditional helmets in safety scores. This isn't just "brand hype"; it is peer-reviewed science.
We believe in being sincere with our customers. While we highly recommend MIPS, a non-MIPS helmet is not "unsafe."
Any helmet that carries an ASTM F2040 or CE EN1077 certification is vastly safer than wearing no helmet at all. If you are on an extremely tight budget, or if you are a very casual skier who only visits the slopes once every few years for low-intensity runs, a standard high-quality Reanson helmet provides excellent linear protection.
However, if you ski more than five days a year, venture onto varied terrain, or value the highest possible level of brain protection, the jump to MIPS is the professional choice.
At Reanson, we don't just "slap a sticker" on our helmets. We collaborate directly with the MIPS team to ensure that the integration is optimized for the specific shape and ventilation of our helmets.
We utilize Multi-directional Impact Testing in our own labs to ensure that our shells, liners, and MIPS systems work as a unified shield. Our goal is to provide "Invisible Safety"—protection that is always there when you need it, but so comfortable and lightweight that you forget you’re wearing it.
Skiing is a sport defined by the joy of movement, but it is also a sport where the unexpected can happen in a split second. The science is clear: rotational motion is a leading cause of serious brain injury, and MIPS is the most effective consumer technology we have to combat it.
Is MIPS worth the extra cost? If you value the long-term health of your brain and want the peace of mind that comes with the best available technology, the answer is a definitive yes.
At the end of the day, your helmet is more than just a piece of plastic and foam. It is the guardian of your memories, your personality, and your future adventures. Choose the gear that treats your safety with the same passion you bring to the mountains.
