A US model down jacket that is lightweight, compact, and pocketable, and is popular overseas. The fabric is made of ultra-thin 10dn ripstop nylon that has been treated to be water-repellent, so it is soft to wear and has excellent heat retention as it can efficiently transfer body heat to the air layer. The shirred elastic on the hood and cuffs, and the adjustable spindles around the hood and hem, prevent cold air from entering from the outside. The hood is designed to fit the head, and it clings tightly to the head, increasing heat retention. Also, the hood does not come off easily even when outdoors in strong winds, so it maintains heat retention. The right hip pocket is double-layered and can be used as a zip pocket when worn, and is also pocketable so you can put a jacket in the zip pocket, making it very small and portable. Not only can it be used as a lightweight outerwear, but it can also be used as a middle layer in the middle of winter with a shell or heavy outerwear. - UK Sma
