The Aggressor Vented Sock takes KLIM’s popular lightweight vented sock and incorporates an all-new technical and performance design to keep you comfortable in warmer weather. The highly-breathable, moisture-wicking above-calf design includes knit mesh panels with comfort padding at ankle, heel, forefoot and sole. Added quick-drying performance nylon materials dry eight times faster than cotton and are twice as soft.
