1. A multilayer breathable fabric, the breathable fabric comprising:
- a) a bicomponent membrane containing;
i) a porous scaffold material having a void volume of at least 60% and an interconnecting microstructure, and ii) a resin composition applied to at least one surface of the scaffold material, wherein the resin partially fill the voids sufficient to create adhesion of the resin to the scaffold material, but not such that all voids within the scaffold are filled, and b) a silver-containing substrate placed in contact with the bicomponent membrane, and being secured to the bicomponent membrane by a discontinuous adhesive layer.

Abstract
A multilayer breathable fabric providing protection against microbial growth, along with anti-odor, anti-static, heat and moisture transfer is disclosed. The breathable fabric includes, in certain embodiments, a membrane containing a porous scaffold material having a void volume and an interconnecting microstructure, and may have a resin composition applied to at least one surface of the scaffold material. The fabric further includes silver-containing substrate placed in contact with the membrane, the silver-containing substrate being secured to the membrane by an adhesive system.
