Good fit no rubbing or chaffing on long rides, I'm 5'11 100kg and purchased XL, I swing between L and XL sizes (L Patagonia, XL Fox, XL ASICS) great autumn shirt for Perth. .....even better it was on sale
This shirt looks and feels great, it means I can get sweaty and still feel good about seeing people I know. The material is super nice and light aswell.
