2XU MA6399a Core Compression Short Sleeve

The 2XU MA6399A Core Compression Short Sleeve is a men's performance compression top designed to provide supportive compression across the upper body during running, training and other demanding activities. It uses lightweight PWX fabric with 360° stretch for flexibility and a close, supportive fit. PWX MESH panels are positioned in key areas to improve breathability and airflow, helping you stay more comfortable as activity levels increase. The raglan sleeve construction allows unrestricted arm movement, while flatlock seams help reduce friction and chafing. Made with 72% recycled nylon and 28% Lycra, the fabric is durable, flexible and quick drying. The compression design is intended to support muscle alignment and postural awareness while helping reduce muscle fatigue and soreness. Its streamlined short-sleeve design makes it suitable for running, gym training, triathlon and other performance-focused activities.
