A protective material having a membrane layer and a sorbent layer. The membrane is a thin-film composite membrane permeable to water vapor but relatively impermeable to organic vapors. The sorbent layer includes activated carbon or other sorbent or reactive material, and captures traces of organic vapor that permeate the membrane layer. The material is particularly useful in intermediate-level protective clothing.
