This synthetic fiber jacket features Omni-Tech waterproof and breathable technology, along with Columbia's unique thermal reflective technology, Omni-Heat Infinity. With a moderate thickness, it's an item that can be worn for a long period from autumn to winter. The Omni-Heat Infinity lining uses a gold dot print pattern to reflect body heat more efficiently without compromising breathability, instantly warming the body. The surface is water-repellent, repelling water droplets and dirt, providing peace of mind when rain or snow suddenly starts. It uses a three-dimensional cut for ease of movement in the arms and elbows. The calm colors and matte texture of the fabric make it easy to use for everyday wear, and it's a highly versatile item that can be worn in various situations. I haven't had a chance to wear it, and it has been stored at home. There are some fold marks from home storage. Please only purchase if you understand that this is a used item.
