Components
The entire ECWCS ensemble (1st generation) consists of polypropylene (1) undershirt and (2) underwear, polyester fiberpile (3) shirt and (4) bib, (5) nylon/cotton trousers, Brookwood Assault or Gore-Tex (6) parka and (7) trousers, liners for the (8) parka and (9) trousers, (10) white (snow camouflage) parka/trousers cover, (11) gloves, (12) glove inserts, (13) mittens, (14) mitten inserts, (15) mitten shells, (16) white mitten shells (snow camouflage), (17) cap, (18) balaclava, (19) nylon socks, boots—both (20) cold weather vapor barrier boots and (21) extreme cold weather vapor barrier boots—and (22) M-1950 trouser suspenders. The system is to be used in an insulated, triple-layering fashion, with the polypropylene undergarments as Layer 1, the polyester shirt/bib, liners and cotton/nylon trousers as Layer 2, and the Brookwood Assault or Gore-Tex outer garments as Layer 3.
The parka and trousers (which have been adapted to the civilian outdoor clothing market) are themselves constructed in a three-layer fashion consisting of an outer layer of abrasion-resistant taslan nylon, an intermediate layer of durably waterproof, windproof, and breathable Brookwood Assault or Gore-Tex membrane (protected with a layer of nylon tricot and originally in a four-color camouflage print), and a hung inner layer of unlaminated nylon. The whole is seam-sealed with Brookwood Assault Seam Tape or Gore-Seam tape.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
