Every young Ultraman fan will adore this long-sleeve compression shirt. The shirt is designed to be worn during physical activities or as a cute cover-up under tanks and tee shirts. Ultraman Compression (long sleeves) are tight, long-sleeved shirts that help support your muscles during a workout. The shirt’s compression helps reduce the risk of muscle strain and fatigue by squeezing the muscles. It also delays the onset of lactic acid buildup, which can cause soreness, for up to 12 hours!
