Sparco MS-4 Single-Layer Racing Suit – XXL | Grey | SFI 3.2A/1 | 002020GR5XXL

The Sparco MS-4 is Sparco’s entry-level single-layer racing suit — SFI 3.2A/1 certified, one-piece construction, in XXL Grey. A well-priced entry point into Sparco’s racing suit lineup for club racing, autocross, HPDE, karting, and track day use where an SFI 3.2A/1 rating satisfies the sanctioning body’s minimum suit requirement. This listing is the XXL in Grey — confirm your size using Sparco’s sizing chart before ordering. Racing suits should fit snugly without restricting movement — an incorrectly sized suit will be uncomfortable and may compromise the suit’s protective function.

SFI Rating — What It Means and When It’s Sufficient

The MS-4 carries an SFI 3.2A/1 certification — the SFI standard for single-layer racing suits, rated for approximately 3 seconds of TPP (Thermal Protective Performance). SFI 3.2A/1 is the minimum racing suit certification accepted by most North American sanctioning bodies for amateur and club motorsport, including:

• NASA, SCCA, and most club racing series at the regional level
• Autocross and time attack events with a suit requirement
• HPDE (High Performance Driver Education) events where a suit is mandated
• Karting series with a fire suit requirement
• Most drag racing classes at the bracket and sportsman level

The MS-4 is not FIA rated (FIA 8856-2000 or 8856-2018) — FIA certification is required for international motorsport and some higher-level North American series. Confirm your specific series’ suit requirements before purchasing — if your sanctioning body requires FIA certification, this suit does not qualify.

Key Features

• SFI 3.2A/1 Certified: Meets the SFI Foundation’s single-layer racing suit standard — the minimum certification accepted by most North American club and amateur motorsport sanctioning bodies
• Single-Layer Construction: One-piece single-layer suit — lighter and more comfortable than multi-layer suits, appropriate for the lower fire exposure risk of club racing and track day use. Multi-layer suits (SFI 3.2A/5, SFI 3.2A/20, FIA rated) provide more fire protection but at a higher price and weight
• Sparco Quality: Sparco is one of the most established motorsport safety equipment manufacturers in the world — Italian-designed, with a product line covering everything from entry-level club suits to FIA-homologated suits used in professional motorsport
• One-Piece Design: Full one-piece suit construction — no gap between jacket and trousers that could expose skin in a fire event
• Grey Colourway: Neutral grey — compatible with a wide range of helmet and glove colour combinations. Available in other colours and sizes (sold as separate listings)

Sizing

This listing is size XXL. Racing suits are sized differently from street clothing — always use Sparco’s official sizing chart to determine your correct size based on your chest, waist, hip, and height measurements. A racing suit should fit snugly across the shoulders and torso without restricting arm or leg movement. A suit that is too large will bunch and shift under a harness; a suit that is too small will restrict movement and may be uncomfortable over a race or track session.

• Confirm your size using Sparco’s official sizing chart at sparco.com before ordering
• Racing suits do not size the same as street clothing — do not assume your street clothing size applies
• Other sizes and colours available — see additional MS-4 listings

SFI 3.2A/1 certified — confirm this certification meets your specific sanctioning body’s minimum suit requirement before purchasing. Not FIA rated. Verify correct size using Sparco’s official sizing chart before ordering — racing suits cannot be returned once worn or used at an event. Pair with SFI or FIA rated gloves, helmet, and (where required) HANS device for complete driver safety equipment. SFI certifications expire — check the suit’s SFI label for the certification date and confirm your sanctioning body’s policy on suit certification age.
