fabric: 59% polyester 41% wool, double layers of knit yarn, each layer is so thick warm and comfortable, stretchable and non-itchy. Neck-warmer fabric: 100% Polyester, Wool Knit Visor Hat with Peak for Men is really warm and breathable for neck, or you can also pull it up to warm the face.
The cable-knit pattern is excellent. There is enough material can be completely pulled down over ears or even neck parts to make you warm in winter; and if you are wearing glasses, the bill and cable will never press the glasses in an uncomfortable way.
The long and sturdy visor bill is great for outdoor activities. It would keep sun, snow and rain out of the eyes or glasses. So we recommend this bill caps to guys who live in cold winter areas with plenty of snow or rain.
