The visor itself is longer and wider than other visor beanie's I've owned, which is great. The added width makes it possible for me to wear sunglasses underneath comfortably. The fold over brim allows me to pull the sides down farther over my ears. The brim's only sewn in place in the back though, so when it's not being worn the front unfolds and flips up. But you just put the hat on, fold the brim under before you go out, and it stays in place.
This particular hat doesn't have fleece lining. (Which is becoming more popular in hats) but it's warm enough as is.
