I'm a school crossing guard and am sometimes at my crossing before the sun comes up. Many drivers have told me that these gloves are easy to see in the pre-dawn hours and are clearly visible during the daylight hours. I purchased 2 sizes: SM and MED. The MED is great because I can wear 'liner' gloves beneath them to help keep my hands warm on cooler mornings. The SM has not yet been delivered. Very comfortable; good flexibility to hold my flashlight without much chance of slipping.
