What Is MIPS in Bike Helmets and How Does It Improve Safety?

Most helmet crashes are angled, not straight-on. A rider goes down, the shell catches pavement at an angle, and the helmet wants to rotate. MIPS — Multi-directional Impact Protection System — breaks that rotation: a thin slip layer in the helmet’s interior allows a few millimeters of glide between your head and the shell, so less twisting motion reaches your brain.

How The Low-Friction Layer Works

The layer sits between padding and outer shell, letting the helmet move slightly relative to the head during an angled impact. Where a standard helmet locks the shell to your skull, a MIPS-equipped helmet gives it travel in the split second that matters — picture a glancing blow at 15 mph: the shell rotates, your head lags, and the slip layer absorbs part of the difference.

• Angled impacts: MIPS targets the rotational forces these produce, which it describes as coming from any angle.
• New and existing models: MIPS says the system works in both new and existing designs, so manufacturers can add it without rebuilding a shell.
• Not a replacement: it is added protection, not a substitute for a helmet that fits correctly and meets applicable certification standards.

Which Helmets Carry MIPS, And How To Spot It

MIPS is an ingredient brand — it sells the technology to helmet makers, who integrate it into bike, snow, motorsport, and climbing helmets.

Spotting it varies: some models show a small yellow Mips logo on the shell or strap; others tuck the layer into the comfort liner, confirmable only through packaging or the product page. Mips’ consumer guidance is to look for the yellow logo when the layer is not visible.

Because each brand integrates it differently, fit, coverage, weight, and certification vary by model. Independent evaluations show how:

Those details come from Transport for NSW’s helmet evaluation reports, which list each model’s AIMS type as MIPS alongside the standards it passed. MIPS and the safety standard are separate checks, and a good helmet passes both.

Does MIPS Make A Helmet Meaningfully Safer?

MIPS is one layer of protection, not a guarantee; its benefit depends on the helmet it is built into. Mips says the solution is built on 25 years of research and development with KTH Royal Institute of Technology and the Karolinska Institute in Stockholm, and describes its helmet test laboratory as part of more than 30 years of continual development.

Where MIPS does not help: fit, coverage, and certification. A helmet that rattles or lacks a current standard is worse than a properly fitted non-MIPS model, whatever layer is inside. MIPS is sold to manufacturers, so you never buy it alone — the cost rides along with the model, which is why it appears in $60 and $250 helmets alike.

The Bottom Line

MIPS adds a low-friction layer that lets the helmet slide slightly against your head in an angled crash, redirecting rotational force. Buy it if the helmet also fits well and carries current certification — the research base and testing lab give the technology real credibility, but fit and the standard stay yours to check.
