The UI-600 Stretch-Fit is Sabelt's top-of-range base-layer top — the compression-style companion to their Stretch-Fit pant, and the layer Sabelt's own professional drivers reach for when weight and fit matter most. Instead of a traditional stitched undershirt, it's built with seamless technology throughout, eliminating the friction points a standard seam creates against skin under a suit through a long stint or race weekend.

The fabric blend — 61% modal viscose, 26% aramidic fibers, 8% polyamide, 4% elastane, and 1% carbon fiber — balances genuine fire resistance with the stretch and breathability you actually want in a base layer, rather than a stiff, purely technical fabric that fights your movement. Fire-retardant printed logos keep the shirt's surface clean and seam-free, and Sabelt notes it's easily customizable on request.

It's homologated to FIA 8856-2018, Sabelt's current fire-resistant racewear standard, so it's legal wherever the rulebook calls for a certified base layer. Made in Italy, sized XS/S through 3X/4X. Available in Black or White.
