How Zone3 compares across published ratings
Work out the real cost per wear
Use the price and realistic wear count to compare long-term value.
Cost per wear is the honest test behind "buy less, buy better": a £200 coat worn 300 times beats a £25 one worn 5 times. It rewards wearing what you own and choosing things built to last.
