What is on this page
The RW-11 Evo range
Sparco describes the RW-11 Evo as made from its lightest fire-retardant material. The long johns meet FIA 8856-2018 and SFI 3.3, so they suit anything from track days and saloon racing to drag racing.
The fabric is breathable and knitted without seams, which removes pressure points under a suit and harness. It is also treated with Sparco’s X-Cool Silver finish, which gives a cooling feel on the skin and has an anti-bacterial effect to help with odour. The long johns come in black or white, in sizes XS to XXXL.
The RW-10 Shield Pro range
The RW-10 Shield Pro uses a mix of light technical fabrics. The long sleeve top gives heat and flame protection to FIA 8856-2018 and SFI 3.3, and is knitted in one piece without seams for a close fit that does not rub.
It has the same X-Cool Silver treatment, and the logos are printed, not stitched, to keep weight to a minimum. The top comes in black, white, black and grey, and navy and grey.

Why underwear matters
Fireproof underwear is worn under the race suit as an extra layer of protection. It puts another layer between you and the heat, and a lot of championships require it. The approval belongs to each item, so it is worth checking the label on every piece against your series regulations.
Garreth’s advice is to buy underwear to the same standard as your suit, so the whole set is covered. Our guide to FIA fireproof underwear explains what you need, and this one covers when it is required in UK motorsport.
