Breathable & Windproof & Waterproof Socks

Merino wool inner lining also helps keep you feet sweat-free and dry. Merino wool transports sweat and moisture away from skin as a vapor. Merino fibers are inherently porous. They’re composed of little plates that moisture vapor can get in between, meaning you're not left feeling wet, cold and clammy after a workout. Merino wool helps you stay warm and dry when you’re moving outdoors.
