The global governing body of competitive skiing (FIS) rates cut-resistant ski gear on a 1-5 star scale. Higher stars mean the fabric withstood more cutting force during standardized testing. This guide covers what each level means, how the test actually works, and what rating you need.
The short version:
- 3 stars = minimum for every FIS Alpine Skiing event, including FIS Masters
- 5 stars = maximum available protection
- The rating comes from the FIS-DITF 2021 test — the only ski-specific cut resistance standard
- Cut-resistant pants are mandatory; shirts and full-body suits are strongly recommended

The Star Rating Scale
Each star corresponds to a specific force threshold — measured in Newtons — that the fabric must withstand without being cut through.
| Rating | Force | What It Means | Compliance Note |
|---|---|---|---|
| 100N | Basic protection | Below the current FIS minimum | |
| 200N | Below mandate minimum | Not sufficient for FIS racing | |
| 300N | Mandate minimum | All FIS Alpine events (minimum requirement) | |
| 400N | Enhanced protection | Above the current FIS minimum | |
| 500N | Maximum available | Highest level on the current scale |
The test threshold rises from 100N at one star to 500N at five stars. That is a laboratory rating, not a promise of a specific injury outcome in a crash.
How the Testing Works
The FIS-DITF 2021 standard is the cut-resistance test named in the FIS Alpine equipment specification.
The test itself is straightforward.
For each level, the fabric must remain uncut across a 200mm test length at the corresponding force.
Three things make this test rigorous:
Tested in three directions. Fabric is cut at 0°, 45°, and 90° because weave patterns affect cut resistance differently depending on angle. Your star rating is determined by your weakest direction. You can't hide a vulnerability behind a strong result at one angle.
4 out of 5 samples must pass. One good result doesn't earn certification. The fabric has to perform consistently across multiple samples.
The documented parameters are the force thresholds, 200mm length, three material directions, and 4-of-5 pass criterion. The specification does not claim that a star rating predicts the outcome of a particular crash.
EN388 vs. FIS Ratings
EN388 is a European standard for industrial cut resistance, designed for factory workers handling sheet metal and glass. Some brands use EN388 certification to market ski products.
The problem: EN388 doesn't test for ski-specific conditions. Different blade, different force application, different failure criteria. A product certified to EN388 but not FIS-DITF 2021 is not FIS-legal for racing, regardless of what the marketing says.
If you're buying cut-resistant ski gear, look for FIS-DITF 2021 specifically.
What Rating Do You Need?
The decisive question is whether your race is FIS-sanctioned.
All FIS Alpine events: 3-star minimum, mandatory. This includes World Cup, Continental Cups, Level 2+ FIS races, and FIS Masters. The garment must carry the specified conformity label; enforcement follows the applicable event rules.
Non-FIS club, youth, academy, and national events: The FIS rule does not automatically apply. Requirements depend on the organizer and national federation, which may impose stricter domestic rules.
Non-FIS club and youth racing: Check the current rule issued by the organizer and national federation. France's FFS requires 3-star tights from U12 upward in 2026/27, although its promotion-race paragraph separately says strongly recommended. Italy's FISI requires minimum 3-star pants for all categories at national, regional, and provincial calendar races and during training.
Do not use an old competition level or last season's guide to decide. First confirm whether the event is on the FIS Alpine calendar; if it is not, check the current domestic rules for that event.

How to Verify Certification
Marketing claims aren't certification. A few ways to confirm what you're actually buying:
Check the conformity label. The FIS specification requires a non-removable label on the back of the lower left leg, above the boot-cuff area. It displays "Conforms to FIS Specifications CRG 2021" and the star level.
Look for "FIS-DITF 2021" specifically. Some brands cite EN388, ANSI, or other industrial standards. These are not FIS certifications and won't satisfy race officials. Only FIS-DITF 2021 counts.
Ask the brand. If the label or certification is unclear, ask the manufacturer for current documentation before relying on a product-page claim.
Brand Comparison
As of this article's last update, this is how the highest-rated current ski-specific cut-resistant leggings we found compare. Each brand links to the option represented here.
| Brand / top option | Highest FIS rating | Approx. price (USD) |
|---|---|---|
| VIX | $449 | |
| DISTON | $545 | |
| Energiapura | ≈$375 | |
| POC | $440 | |
| SHRED / Iron-IC | $300 | |
| SYNC | $449 |
Prices are approximate USD snapshots of the linked adult options and vary by market. For FIS racing, the garment itself must show the CRG 2021 label and at least 3 stars; the linked SYNC option falls below that minimum.
How to Verify Any Product
- Check the CRG 2021 conformity wording and star count on the physical garment.
- Confirm the certified area provides the required coverage.
- Check the manufacturer's current fit, care, return, and replacement guidance.
FAQ
Who created the FIS star rating system?
The published Alpine equipment specification identifies the FIS-DITF 2021 test standard. VIX's development records also document Victor Wiacek's early ski-edge test machine and his work with FIS, but that company history is separate from the requirements in the official specification.
Do star ratings degrade over time?
The certification applies to the product as certified by the manufacturer. FIS says the garment must be used without alteration and in accordance with the manufacturer's instructions. Follow that brand's care, inspection, and replacement guidance rather than a universal season count.
Is 5-star protection overkill for club racing?
3-star fabric passes the FIS test at 300N; 5-star fabric passes at 500N. Both are supplementary protection, and neither predicts a particular crash outcome. Whether the additional tested margin is worth the cost depends on your situation. We're biased, but we think it is.
Can EN388-rated gear be used for FIS racing?
No. FIS requires FIS-DITF 2021 certification specifically. EN388 is an industrial standard for factory workers — different blade, different test, different purpose. Products certified only to EN388 are not FIS-legal, even from well-known brands.
What does the conformity label look like?
It is a non-removable label on the back of the lower left leg, above the boot-cuff area. It shows the wording "Conforms to FIS Specifications CRG 2021" and the star level. It provides visible evidence of the garment's conformity; enforcement follows the applicable event rules.
