This hi-vis T-shirt is a lightweight short-sleeve top for work in warm weather where you need to be seen. The breathable sports-type knit helps you stay cool and dry through active shifts.
Reflective tape adds visibility, and the UPF 40+ fabric gives your skin added sun protection outdoors. A taped neck seam keeps the crew neck comfortable against the skin.
