This is a Corona G-1 parka coat. Navy, size L. It's a Thinsulate jacket that boldly uses Epic fabric adopted by the US military. You can wear thick inner layers underneath, and the moderate Thinsulate provides comfort even with just the jacket alone during the chilly seasons of spring and autumn. The weight is also considerably reduced, offering a feel similar to outdoor brands. I've worn it once or twice a year since I bought it new. The condition is considered to be in the category of "beautiful condition." If anyone is interested, please consider purchasing it.
