防寒服用织物（ECWCS）

用于:	第二代 Extended Cold Weather Clothing System 大衣和长裤
用户:	美国海上军团
指标:	MIL-PRF-44187D
NSN:	Parka 8415-01-421-9245 through 9280 Trousers 8415-01-451-2773 through 3260

特点:

适合于温度范围 -60^oF to 70^oF
Trousers have Cordura seat and knee patches for abrasion resistance, cargo pockets and belt & suspender loops
Parka has a stowable hood, two breast pockets, two shoulder pockets, large cargo pockets (with handwarmer pockets behind them), two-way full front zipper, Velcro closures on wrists, underarm ventilation, Cordura reinforced elbows, and rank tab at center chest
GORE-TEX^® fabric meets and exceeds requirements of MIL-PRF-44187D
织物结构：2.8 oz. nylon Taslite/GORE-TEX^® film/1.5 oz. nylon tricot
Breathable - GORE-TEX^® fabric allows moisture vapor to move away from skin
防风，有效阻隔沙和微粒；
Non-wicking barrier applied to cuffs of parka/trousers & lower hem of parka
Unlined parka has reduced bulk and weight
Parka is 4 inches wider in chest, and 2 inches longer than 1st Generation ECWCS
Separate attachable hood for Zones V - VII (optional fur ruff can be attached to hood)
Oversized to be worn over insulated layers
