Básar Base Layer Bottoms Men

The Base Layer Bottoms Iceland Swears By

In Iceland, they call them Básar tights—and there's a reason they're a staple in one of the world's most demanding climates. These base layer bottoms are crafted from 100% Merino wool that regulates body temperature by controlling evaporative cooling, keeping you warm when it's cold and cool when you're working hard. Soft next to skin with flat needle stitching for no-rub comfort, the Básar tights naturally move moisture away from your body. Equally perfect for backcountry missions or lounging by the fire after a long day outside. This is 66 North's foundation layer—the one that makes everything else work better.
