Frequently Wear a Walz cap. Have several, a wool one with ear flaps for winter, plus a couple of synthetic ones. Wear them cycling with brim down in front to keep sun out of eyes or with brim up for more visibility. If it rains, wear brim to the rear to reduce rain down my neck. Wear one under my winter parka as a thermal barrier. If the ice goes out in a couple weeks, will wear one fly fishing to help keep bugs out of my hair. Often wear a cycling cap, cycling or not.
