This is an original product from Seabees. The US military's cold-weather clothing system, introduced in the 1980s, evolved into the 3rd generation in the 2000s, combining seven layers (types) of clothing from LEVEL1 to LEVEL7. The GEN3 LEVEL7 jacket is also known as the "Marshmallow Suit" by the Army and the "Happy Suit" by the Navy. LEVEL7 is the final layer of the ECWCS and can withstand environments as cold as minus 46 degrees Celsius depending on the inner layers. It is not intended to be worn during combat, but rather during standby at forward bases, and has only two pockets that also serve as hand warmers. The lining uses "Sorona," a high-performance polyester made by DuPont in the USA. Sorona polymer is as light and warm as down, with excellent moisture retention, making it less prone to stuffiness and comfortable, with high compression and recovery properties. ・Size: XL / Regular ・Color: Coyote Width 62cm, Length 76cm Please note that these are flat measurements and may have slight variations due to amateur measurements.
