The 5.5 UltraWeld Jersey is unmatched in quality and fit! Engineered with integrated air vents and laser-cut perforations, this jersey is exceptionally lightweight and breathable. The stretch material allows for maximum flexibility and provides a slim fit. You can easily wear a protector under or over the shirt! The collar is specifically designed for Leatt neck protection. For added comfort, the seams on the underside and wrists are sealed. Additionally, the jersey is reinforced with Brush Guard, a thin film that protects the torso from wear and tear.
