The Portwest ES478 Essential Hi-Vis T-shirt is a lightweight, short-sleeved hi-vis layer for work in hot weather where you need to stay visible. The sports-type knit fabric lets air through and moves moisture away from the body, so it suits long, warm shifts outdoors.
A wicking finish speeds up drying and helps stains wash out. The UV-rated fabric adds sun protection on bright days.
