The UI-600 Stretch-Fit is Sabelt's top-of-range base-layer pant — the compression-style counterpart to the roomier Regular Fit line, and the version Sabelt's own professional drivers reach for in the paddock. The close, slim fit isn't just about looks: a tighter base layer under a suit means less bunching, fewer pressure points at the harness and seams, and a cleaner overall fit stack when you're layered up for competition.

It's built with seamless construction throughout, cutting down on the friction points a traditional stitched underlayer creates against skin, and the lightweight fabric keeps it from adding bulk under a suit even on long stints or hot days. Fire-retardant printed logos mean there's no added material or stitching where a sewn patch would normally sit.

Homologated to FIA 8856-2018, Sabelt's current fire-resistant racewear standard, it's legal wherever the rulebook calls for a certified underlayer — from club-level track days through wheel-to-wheel competition. Made in Italy, sized XS/S, M/L, and XL/XXL. Available in Black or White.
