description @ This invention provides a waterproof and breathable elastomeric polytetrafluoroethylene layered article or fabric for use in rainwear or other protective articles. The layered article can for example, exhibit elastomeric properties of stretch to break of 275% in the machine direction, and 145% in the transverse direction and a total stretch recovery of at least 39% after being stretched to 75 % extension for 100 cycles. The waterproof and breathable elastomeric polytetrafluoroethylene layered article can be bonded to a stretch fabric to form a composite fabric which is durable and possesses a moisture vapor transmission rate exceeding 1000 gms/m2/day, and preferably above about 2000 gms/m2/day.
