The Sabelt UI-601 Bicolor Pant is the bottom half of Sabelt's top-of-range UI-601 underwear system, sharing its construction approach with the matching UI-601 Bicolor Top: fully seamless, slim-fit, and built to sit under a driver's suit without bunching, chafing, or extra bulk at the waist and legs.

The bicolor design is functional rather than cosmetic. Strategic stretch panels in a darker material are placed at key flex zones through the hips and legs, letting the fabric move with the driver through pedal work and seating position rather than resisting it. The seamless knit construction keeps stitching off pressure points entirely, which matters over a long stint in a fixed driving position.

Lightweight by design and finished with a printed logo rather than a stitched patch, this is Sabelt's top-of-range pant underwear — built for drivers who want a base layer that disappears rather than one they have to work around. FIA 8856-2018 homologated for circuit racing, rally, and endurance use, it's made in Italy. Complete the system with the matching UI-601 Bicolor Top and Balaclava for consistent fire protection and feel across every layer.
