Hey all, I've worn my set of Oakley Flak Jackets for years and love them. I went to the store recently and I like the look of the Batwolfs and tried them on. They fit well but I felt slight pressure on the sides of my head from the ear pieces. Do Oakley frames stretch or break in at all or should I take this slight pressure to mean these frames aren't for my head? I don't want to wear these for driving for hours if the pressure will build over time and cause a headache. Thanks!
