Frequently Asked Questions

Everything you need to know before you buy

What is the difference between SFI-1 and SFI-5 suits?
SFI-1 (SFI 3.2A/1) suits are single-layer and rated for entry-level racing like dirt track, karting, autocross, and drifting. SFI-5 (SFI 3.2A/5) suits are double-layer and provide significantly more thermal protection - they're required for NASCAR, NHRA, sprint car, and most sanctioned professional events. If your racing sanctioning body requires SFI-5, you must use a double-layer suit.
What does SFI certification mean?
SFI (SEMA Foundation Inc.) certification means the suit has been independently tested by the SFI Foundation for thermal protection performance (TPP). Each certified suit has an SFI tag with a unique serial number. SFI ratings are required by all major US racing sanctioning bodies including NASCAR, NHRA, SCCA, IMSA, and most local tracks.
How do I find my correct size?
Use our size chart on this page (click "Size Guide" above). Measure your chest, waist, and inseam. The suit should fit snugly but allow full range of motion. If you're between sizes, we recommend sizing up. Our 30-day return policy means you can exchange if the fit isn't right.
How long does shipping take?
All orders ship free within the US. Pre-made suits in stock ship within 4-5 business days. You'll receive tracking information via email once your order ships. If you need a suit faster, contact us at (409) 404-0962 and we'll do our best to accommodate.
What is Nomex and why does it matter?
Nomex is a flame-resistant meta-aramid fiber made by DuPont. Unlike chemically treated fabrics that can lose their fire resistance after washing, Nomex is inherently fire-retardant at the molecular level. It won't melt, drip, or support combustion. It's the same material used by firefighters, military pilots, and Formula 1 drivers.
Can I wash my Nomex fire suit?
Yes. Machine wash cold on a gentle cycle with mild detergent. Tumble dry on low heat. Do not use bleach, fabric softener, or dry clean. Nomex retains its fire-retardant properties through washing - it's built into the fiber, not applied as a coating.
What is your return policy?
We offer a 30-day hassle-free return policy. If the suit doesn't fit or doesn't meet your expectations, return it in original condition for a full refund or exchange. Return shipping is free. Contact us at (409) 404-0962 or email support@fervogear.com to initiate a return.

Best value SFI-5 suit on the market. I've worn RaceQuip and Sparco before - this suit fits just as well at half the price. The radial arm design actually lets me steer without feeling restricted. Passed tech inspection first try.

★★★★★ Verified Purchase
SFI-5 certified and fits perfectly. Needed an SFI-5 suit for NHRA bracket racing. This delivered exactly what I needed. The Nomex feels premium, the D-rings are solid, and the two-piece design makes it easy to get on/off between rounds.

Incredible quality for the price. Running late models at my local track and this suit holds up race after race. The stretch panels make a huge difference in comfort during long feature events. Already recommended to my crew.

Great suit, fast shipping. Ordered on Monday, had it by the following week. Fits well - I'm between M and L and went with L. The quality of the Nomex and stitching is on par with suits twice this price. Only wish they had more color options.
