The Wool Vest is humankind’s oldest insulator, and its best. No matter what technical fabrics boast about performance, nothing can beat the results of nature’s test lab. As far as history remembers, wool has proven itself with time and usage, making it the clear choice for a critical insulation layer. The waxy resin on the wool fibers give it superior breathability, adaptability, and the ability to retain heat when wet (an indispensable defense against hypothermia). The Best Made Company sticks to tradition when making their Wool Vest, with 100% shorn and scoured sheep’s wool, double-thick at the collar to keep the biting wind off your neck, and a two-way zipper to enhance the vest’s natural temperature regulation. We trust that evolution figured this one out.
