Hi Vis Vest, Class 2, Yellow

A class 2 hi vis vest in yellow, worn over whatever you already have on.

Ventilation is the useful part. A solid vest in summer becomes an extra layer of heat by mid-morning, while one built to breathe moves air through it and stays wearable when it is genuinely hot. Class 2 is the specification, and yellow is the colour that reads first against most backgrounds. Multi-colour panels break up the block of yellow so the shape of a person stands out rather than a flat rectangle.

Vests like this get lost, borrowed and left in vehicles, so it is worth having more than one. Size it to go over a jacket rather than over a tee, because the version you need in winter is the version that has to fit over everything else. Straightforward kit that only matters on the day it matters, which is the day you are glad you had it.
