FieldCore's 4L jacket offers excellent heat retention and durability. Although it's a 4L, it fits me perfectly at 175cm. I think layering is also possible. I wore it while commuting on my motorcycle, but I've sold the bike, so I'd love for anyone looking for cold-weather gear to try it out. m(_ _)m - Color: Gray - Inner Material: Metallic material - Brand: FieldCore - Size: 4L - Features: Heat retention and durability Thank you for viewing.
