| Lining | Optional FR lining | Mandatory moisture barrier |
| Seams | Lock-stitched with FR thread | Triple-stitched FR thread |
| Cuffs/Neck | Elastic with FR properties | FR-only, often aramid knit |
🎯 Our suits use Kevlar stitching, Nomex outer shells, and breathable linings — meeting both standards.

❓ Frequently Asked Questions
Q: Can I use an FIA suit in an SFI league?
A: Yes, in most U.S. leagues. But the reverse is not always true — SFI suits are usually not accepted in FIA-level karting or F4.
Q: What does SFI 3.2A/5 actually mean?
A: It’s a safety level where the suit must resist 10 seconds of direct flame and provide a Thermal Protection Performance (TPP) of 19+.
Q: What’s the cost difference?
A: FIA certification can add $40–$100/unit in cost due to materials and homologation. SFI suits are more budget-friendly.
