Fabric & Fit
Named after Alaska's Kenai Peninsula—often called the "Alaskan Playground"—these base layer pants are built for adventure in frigid conditions. The heavyweight interlock knit (400 g/m²) delivers maximum warmth for extreme cold, making them ideal for ice fishing, snowmobiling, skiing, and any activity where temperatures plunge below zero. Pairs perfectly with the matching Kenai Heavyweight Crew for complete cold-weather coverage. Regular fit offers a comfortable silhouette with room to breathe—size down if you prefer a more athletic, compression-style fit.
