Get in touchshield_question Always check the jacket's own size chart before you buy. Sizes are not standardised between brands, or even between models from one brand. Armour only protects where it actually sits, so a jacket or trousers that shift on you are worse than they look on the size chart. The ranges here are general guidance and haven't been matched to a specific manufacturer's chart.
