The SympaTex membrane is made of hydrophilic polyether-ester block copolymer, which is closed (i.e. it has no pores). Like its more common polyurethane equivalent, it can also be referred to as a monolithic membrane. No water can get in from the outside, but water vapour molecules are transported through the membrane from the inside to the outside by way of an absorption and evaporation process. This moisture transfer through the membrane is what is referred to as "breatheability".
