The Portwest S278 is a long sleeve hi-vis T-shirt for work where you need to be seen. It is made from Portwest’s Cotton Comfort fabric, a knit with a high cotton content that feels soft against the skin.
The long sleeves cover your arms fully, and reflective tape adds visibility in low light. The fabric wicks moisture to help keep you cool and dry through a working shift.
