This vest is filled with plenty of down, just like the classic down jacket. Its size is perfect for layering over a thick knit. The outer surface is made of nylon washer material with an initial water-repellent finish, and this year we are using a softer type that is lighter and more comfortable to the body. The reversible glen check pattern is a great accent and is very useful. [GERRY] An American outdoor brand with a long history of more than half a century since its birth. Its roots lie in the manufacture of sturdy climbing and camping gear for mountain troops. After the war in the United States, as the outdoor leisure population increased against the backdrop of high economic growth, the company began to use its reliable technology to make functional gear for campers, fishermen, hikers, and climbers, laying the foundation for the current outdoor brand.
