Introducing the US Army ECWCS Gen3 POLARTEC Fleece Jacket in FOLIAGE. Official Name: JACKET, FLEECE COLD WEATHER (GEN III) This highly popular and globally sought-after US military-issued ECWCS system GEN 3 fleece jacket has arrived. ECWCS (EXTENDED COLD WEATHER CLOTHING SYSTEM) is a layering system adopted by the US military in 1986, known as the extended cold weather clothing system. Items are available in stages from LEVEL 1 to LEVEL 7, allowing for adaptation to various climates and temperatures by layering as needed. The POLARTEC used is made by knitting polyester fibers using a special technique, followed by dyeing, brushing, and heat treatment. It is lightweight, breathable, insulating, durable, and quick-drying, making it a high-performance material that perfectly meets all the requirements of outdoor clothing materials. The long pile also creates a soft, fluffy feel, which is a major feature. It features raglan sleeves to ensure a wide range of motion, large mesh inner pockets, and side pockets. Highly elastic grid fleece (Power Dry Grid) is used on both sides under the arms to improve elasticity and breathability. In addition, the shoulders near the armholes, where friction occurs when carrying a bag, and the elbows and undersides of the arms, which experience the most wear and tear in daily life, are reinforced with nylon fabric, making it extremely durable. The fleece, which is very popular within the ECWCS, is a rare item that has become increasingly difficult to obtain in recent years.
