The Cotopaxi Trico Hybrid Vest is perfect for everything from cool-weather hikes to campfires.. We like that it has a durable design because the warm insulation is made from 100% recycled polyester and the shell and lining are made from 100% recycled polyester taffeta. Two hand pockets keep your hands warm on the go , and the chest pocket with a zipper will securely store the smallest items.
