Constructed from supremely comfortable, lightweight Bastien Melange Fabric that provides extra protection in cool weather while maintaining moisture-wicking features. The underarm panels are composed of SpeedPro fabric – the same fabric as our cycling jerseys to continually provide breathability. With reflective accents, set-in sleeves, and flatlock stitching, this Technical T-Shirt eliminates undesirable seams and moisture, and keeps you feeling comfortable whether you’re on or off the bike.
