Breathable garments allow air exchange between the wearer’s body and the environment. When a protective garment is breathable, the fabric or material provides air and moisture vapours. Breathability in protective garments is usually achieved through the use of certain fabric technologies or construction techniques that allow air molecules to pass through the material while having the ability to block larger liquid water droplets from penetrating the fabric. The garment can still provide protection while allowing heat and moisture to escape the body.
