Crew and mechanics wear size guide

Pit and workshop kit is sized on the same ladders as driver kit, so if you already know your race suit or glove size you know this too. The one thing to watch is that overalls come in two systems: Sparco use letters and OMP use the numeric ladder.

Overalls

Sparco MS-4 and MS-5, and the Proban suitLetters, XS to XXL.▼

Letter	Equivalent	Chest (cm)	Waist (cm)
XS	44 / 46	86 – 93	74 – 81
S	48 / 50	94 – 101	82 – 87
M	52 / 54	102 – 109	88 – 97
L	56 / 58	110 – 117	98 – 105
XL	60 / 62	118 – 125	106 – 113
XXL	64 / 66	126 – 133	114 – 121

These are the bands from Sparco’s own body size chart, which is what their letters follow. The OMP Proban race suit is also sold S to XXL and uses the same pattern.

OMP Summer and Blast EvoNumeric, 44 to 64. The same ladder as OMP race suits.▼

Size	Chest (cm)	Waist (cm)	Height (cm)
44	87 – 91	71 – 75	155 – 165
46	91 – 95	75 – 79	158 – 170
48	95 – 99	79 – 83	165 – 175
50	99 – 103	83 – 87	170 – 180
52	103 – 107	87 – 91	170 – 183
54	107 – 111	91 – 95	177 – 187
56	111 – 115	95 – 99	182 – 190
58	115 – 119	99 – 103	185 – 195
60	119 – 123	103 – 107	187 – 198
62	123 – 127	107 – 111	190 – 200
64	127 – 131	111 – 115	190 – 200

Mechanics overalls are meant to be roomierUnlike a race suit, you want room to crouch, reach and kneel in these all day. If you are between two sizes take the larger one, which is the opposite of the advice for a driving suit.

Gloves

Measure around your knuckles, across the widest part of the palm, leaving the thumb out.

Letter	Numeric	Sparco palm (cm)	OMP palm (cm)
XS	8	20.5 – 21.5	20.8 – 21.5
S	9	21.5 – 22.5	21.6 – 22.3
M	10	22.5 – 23.5	22.4 – 23
L	11	23.5 – 24.5	23.1 – 23.7
XL	12	24.5 – 25	23.8 – 24.8
XXL	13	25 – 25.5	24.7 – 25.4

Sparco and OMP agree within half a centimetre throughout. A mechanics glove should be a little looser than a driving glove so you can get it on and off quickly with dirty hands, so if you are on a boundary take the larger.

Shoes

The Sparco Fast and Chrono mechanics shoes use the standard Sparco ladder. Measure heel to longest toe, standing, and work from the bigger foot.

EU	UK	Foot length
37	4	24.3 cm
38	5	25.0 cm
39	5.5	25.7 cm
40	6.5	26.3 cm
41	7	27.0 cm
42	8	27.7 cm
43	9	28.3 cm
44	9.5	29.0 cm
45	10.5	29.6 cm
46	11	30.3 cm
47	12	31.0 cm
48	13	31.6 cm

The Alpinestars Radar V2 mechanics shoe uses the Alpinestars ladder instead, which carries half sizes Sparco does not: UK 7 is an EU 40.5, UK 9.5 is an EU 43.5 and UK 11 is an EU 45.5. Go by the UK size on that one. It also runs up to UK 14.

Shorts

The Sparco Bermuda cargo shorts run S to XXL on the same letter bands as the overalls above, sized on your waist rather than your chest.

A note on approvals

Some of this category is FIA 8856-2018 approved and some is not. The Sparco Tide Meca and R-Meca gloves, the OMP Pro Mech gloves and the Sparco Fast and Chrono shoes carry the driver-standard approval, which matters if you are working on a refuelling stop. The Workshop EVO gloves, the cargo shorts and the MS-4 and MS-5 overalls are workshop kit. The approval is listed on every product page.

Sparco bands from sparco-official.com. OMP numeric ladder from their published suit chart. Glove and shoe ladders as verified for our racing glove and racing boot size guides. All checked 2 August 2026.

What size should I order?
Sizes run from XS to XXL. Crew kit gets worn over normal clothes for long days, so if you are between sizes, take the larger one for comfort. Ask us if you want measurements checked before ordering.

Is this fireproof?
No, this is workwear rather than homologated fire-resistant kit. It is right for the workshop and general paddock duties; for refuelling or live pit work in series that require it, look at the FIA 8856 crew garments in the range.

How do I wash it?
Cool and gentle, no bleach or fabric softener, air dry. That preserves any fire-resistant treatment and keeps embroidery and badges in shape season after season.
