Headbands control sweat and flyaway hair without trapping heat, keeping your vision clear during interval sessions or summer long runs. Running hats provide sun protection for exposed faces and scalps, or trap escaping body heat during winter miles when temperatures drop below comfortable. Gloves keep your fingers functional when cold weather threatens to cut outdoor sessions short, with touch-screen compatible options that let you control your watch without exposing bare skin. Technical running socks prevent blisters through moisture-wicking fabrics and targeted cushioning in high-friction zones. Sunglasses protect your eyes from UV damage while eliminating the squinting that reduces performance on bright days, with secure fits that stay put through sweat and head movement.
