How does Breathable Material work?
The key to the enhanced performance of breathable materials is in their advanced inner membrane – most commonly TPU (Thermoplastic Polyurethane). This microporous laminate is a Hydrophilic membrane, the structure of which allows moisture to be wicked away from the body and transferred through the fabric to the outside in the evaporated state. The micro-pores in the TPU laminate are large enough to allow moisture vapour (perspiration) out, but far too small to allow water molecules in, making the fabric totally waterproof.
