The Radwear Silver Series mechanic's gloves would have impressive construction for the price even without being hi-viz. Smooth interior seams, reinforced rubber pads on the forefinger and thumb, and light padding on the palm make this very comfortable to wear, and the bright back with reflective tape make it visible from a distance. The black synthetic palm hides dirt and stains.
Woven nylon/spandex back, synthetic palm, open wrist with partial elastic, straight thumb
