SJT vs SJTW outdoor cords: SJTW wins for weather resistance and longevity

SJTW has a weather-resistant jacket that handles rain, snow, and sun, while SJT lacks that protection and cracks over time. Both have the same gauge and rating (300V, -40°C to +60°C), but SJTW costs a few bucks more and lasts years longer. Don’t save two dollars on the cord that carries electricity through your wet yard.
