I live and ride in Washington State, year 'round. I use leg and arm warmers when it's above 45°. They are the best. I never take tights, outer pants, any of that stuff when I go touring. Everything I wear on the bike will fit in a jersey pocket when I take it off: jacket, vest, leg warmers, arm warmers. I use Voler Jet High Viz wind jacket and vest, very light and stuff well. I also use their arm and leg warmers. Some people prefer putting their leg warmers on the outside of their shorts, but most wear them inside.
