Elevate your active trail adventures with our Sigma short sleeve performance tee. Its mesh-knit fabrication enhances wicking and reduces wet cling when you sweat, as well as improving breathability to keep you cooler in hot conditions. The fabric is also stretchy to allow for range, with a fitted design to assist streamlined movement. All underarm and side seams have been removed to cut down rubbing and irritation hot spots, while reflective print graphics improve visibility for safer activity at night. Lightweight and quick-drying, the Sigma tee is designed for trail running, climbing, summer hiking and other high intensity outdoor adventures where you need to keep your cool.
