A MIPS bike helmet is a standard bicycle helmet that includes a built-in slip-plane layer designed to reduce rotational forces on the brain during angled impacts.
If you’ve seen the yellow MIPS logo on helmets lately, you may have wondered if it’s a brand or a gimmick. It’s neither. MIPS—short for Multi-directional Impact Protection System—is a safety technology that tackles a kind of crash force that conventional helmet foam alone doesn’t handle well. A MIPS bike helmet looks and fits like any other helmet, but inside it carries a low-friction layer that lets the helmet slide slightly on your head during an angled impact, aiming to lower the rotational energy reaching your brain.
What Is the MIPS System?
MIPS is a Swedish technology, developed by a company founded in 2001, that adds a thin, low-friction layer between the helmet’s foam liner and the comfort padding. According to the MIPS Protection System official site, the layer is designed to move about 10 to 15 millimeters in any direction during an oblique impact. That movement is intended to mimic the way the brain is naturally cushioned by fluid inside the skull, redirecting rotational forces away from the head. Importantly, MIPS is not a helmet brand—it’s a licensed technology used by dozens of manufacturers in bike, ski, snowboard, equestrian, and even construction helmets.

How Does a MIPS Helmet Work?
In a real-world crash, few impacts are perfectly straight-on. Most are angled, where the head rotates on impact. Standard helmet foam handles the linear part of that force, but rotation is linked to concussions and brain injury. During an angled hit, the MIPS layer slides inside the helmet, allowing the outer shell to move independently of the head. This relative motion helps reduce the rotational acceleration transmitted to the brain. The system does not replace the helmet’s foam or its safety certification (e.g., CPSC in the U.S.); it works as an additional defense specifically for oblique impacts.
Correct integration matters: the MIPS layer must be built into the helmet by the manufacturer, not added afterward. The fit may feel slightly different because of the extra liner, but most riders adjust quickly.
Common Misconceptions About MIPS Helmets
A frequent mistake is treating MIPS as extra padding. It’s not more foam—it’s a slip-plane. Another is assuming a MIPS helmet is “concussion-proof.” No helmet eliminates all risk; MIPS is one engineering approach to a specific type of impact. Some people confuse the acronym order (it’s Multi-directional Impact Protection System), and others treat MIPS as a brand rather than a technology licensed to many brands. Finally, MIPS does not make a helmet universally safer in every crash—its benefit is confined to rotational forces from angled impacts. A helmet without MIPS still meets safety standards; a helmet with MIPS adds an extra layer of protection for certain scenarios.
FAQs
Is MIPS the same as a helmet brand?
No. MIPS is a safety technology developed by a Swedish company, not a brand of helmet. Many helmet manufacturers—such as Giro, Bell, and Specialized—license the MIPS system and integrate it into their own models. You can find MIPS in helmets across different sports and price ranges, but the technology is always from MIPS AB.
Does a MIPS helmet replace the need for a standard safety certification?
No. MIPS is an added feature, not a replacement for required certifications like CPSC, ASTM, or EN 1078. Every MIPS helmet sold in the U.S. must still pass the same impact tests as non-MIPS helmets. The MIPS layer works alongside the foam liner to address rotational forces that certification tests do not measure.
Can MIPS be added to an existing helmet?
No. The MIPS slip-plane must be engineered into the helmet during manufacturing. There is no aftermarket MIPS insert that fits any helmet. If you want the technology, you need to buy a helmet that comes with it built in. Some older helmets may not have a MIPS version available, but many current models offer both MIPS and non-MIPS options.
