Every piece of XRACEKIT gear starts with the right raw material, because safety and durability begin long before the first stitch. Our motorcycle suits use full-grain cowhide and kangaroo leather sourced from certified tanneries, the same grade trusted across professional motorsport. Our karting suits use fire-resistant fabric built to FIA and CIK homologation standards. Every batch is tested for abrasion resistance and tear strength before it reaches production.
Behind every XRACEKIT product is a team of pattern cutters with real motorsport apparel experience. Double and triple stitching is used on every high-stress seam — shoulders, elbows, knees and crotch — the exact points where standard garments fail in a slide. Every suit passes a multi-point inspection before it ships, and our armor sits in anatomically shaped pockets so it stays in place during impact, not just during a showroom try-on.
Most racewear brands add layers of margin between the factory and you: importer, distributor, retailer. We work directly with our manufacturing partners and sell straight to you — no agents, no inflated retail markups. That means CE-certified, professionally constructed gear at a price that reflects what it actually costs to build well, including full custom and personalized options without the huge minimum order quantities traditional brands require.
A racing suit that fits badly is not just uncomfortable, it's dangerous. That's why we treat sizing as seriously as any other part of the product — detailed measurement guides for every item, based on real body measurements, not generic S/M/L labels. If the fit isn't right when your order arrives, our 30-day hassle-free exchange policy means you can get the correct size without cost or complication.
