GU Bear Merino Wool Long Sleeve
Merino wool offers numerous advantages: It provides good insulation, transports moisture and has anti-static properties; it doesn’t itch, smell or crease much; it is lightweight and keeps its shape. And it does all this in a completely natural and sustainable way.
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. Synthetic fabrics are not porous.
