The novel composite includes a first layer which may be in the form of a film or coating, of a water and particulate material impermeable, vapor permeable material which is also resistant to sebaceous excretions. A second layer of a vapor permeable stretch fabric material is also provided. Disposed between said first and second layers is a third layer of vapor permeable stretchable fabric material containing a particulate adsorbent material for the noxious substances. Depending upon the application, other optional layers may be included. The composite is stretchable to an extent of 30 to 500% and is intended for use in making close-fitting clothing to protect the wearer from noxious substances.
