Construction & Materials
Crafted from high-grade drum-dyed leather, the V4.2 suit is built to withstand the demands of track riding while maintaining flexibility and comfort. Strategically placed stretch panels allow natural movement in aggressive riding positions, while reinforced impact zones provide added confidence where it matters most.
The addition of forged carbon fibre inserts at the shoulders and knees not only reduces weight but also improves slide performance and durability in high-impact scenarios.

Fit, Comfort & Ergonomics
The V4.2 has been refined with updated ergonomics to offer a more natural, race-focused riding position. Pre-curved arms and legs reduce fatigue, while stretch panels across key areas ensure unrestricted movement on the bike.
A breathable internal lining helps regulate temperature, while improved ventilation zones keep airflow consistent—even during high-intensity sessions.
