Klim Aggressor Sock 3.0

The KLIM Aggressor Sock 3.0 is the warmest and most heavily cushioned sock in the Aggressor lineup, built for riders who refuse to let cold feet ruin a day on the snow. Constructed with a premium Teton Merino Wool blend, the Aggressor 3.0 delivers exceptional warmth, moisture management, and next-to-skin comfort while helping regulate temperature inside insulated riding boots. Full Terry Loop construction provides maximum cushioning and insulation throughout the sock, while reinforced wear zones improve durability in high-stress areas. Arch and ankle support bands help reduce fatigue during long rides, and strategically placed flex zones minimize bulk and pressure points inside boots. Whether you're tackling sub-zero trail rides, spending hours ice fishing, or simply struggle with cold feet, the Aggressor Sock 3.0 is basically built for riders who think warm feet are non-negotiable.
