Specify the breathability metric, test method, units and conditioning before comparing hardshell materials or approving a claim. Different methods can produce results that are not directly comparable. Review the selected laminate’s report and distinguish material performance from garment ventilation features. Keep published claims tied to the tested construction and avoid assigning a jacket rating from an unrelated fabric report.
