The Sabelt UI-601 Bicolor Top is the shirt half of Sabelt's top-of-range UI-601 underwear system — the same line that includes the UI-601 Bicolor Pant and Balaclava. Unlike the balaclava, which trades a seamless build for lateral seams to manage helmet pressure, the Top and Pant go fully seamless, giving the garment a compression-style, slim fit with no stitching to create hot spots or bunching under a driver's suit.

The bicolor design isn't cosmetic. Strategic stretch panels in a darker material are placed at key flex zones, letting the knit move with the driver through the shoulders and torso rather than fighting them during hard inputs. It's lightweight by construction and finished with a printed logo instead of a stitched patch, keeping the garment low-profile under a suit.

This is Sabelt's top-of-range top underwear — the piece the brand notes its own drivers favor in the paddock for how little it weighs and how it disappears under a suit. FIA 8856-2018 homologated for use in circuit racing, rally, and endurance events, it's made in Italy and available across a full size run. Run it solo or complete the system with the matching UI-601 Bicolor Pant and Balaclava.
