It's a bigger style, but not HUGE like a big apple.
I just got it, but am sure it will be very warm. Good for my Alaskan, or any other cool/cold climate. I bought the 7 5/8 and it fits perfect. I wear an XL in most caps (L XL is normally too tight) So, I would say it's true to size. It's very quality. Should last a lifetime, and add nice variety to my collection. If I could go back, I would buy it again.
