Check local visibility

Action

  • Add reflective details at ankles, wrists, or other moving points so drivers catch motion early.
  • Keep at least one high-contrast element on your torso.
  • If you are biking, use a front white light and rear red light in addition to reflective details.

If you are choosing from regular clothing, start with white and add reflective details at moving points. It lands at about 95% of the average high-vis score here.

If you are packing one option for Marina / Presidio low light conditions, make it white if that is what you already own. If you have high-vis gear, bright white still performs best overall.
