When choosing a base layer, it's part science and part personal preference. Our Merino wool base layer lineup features our midweight Aspect line and our heavier Inversion line. Whether you run hot or cold, whether you're looking for a do-it-all layer or one for the coldest of days, Ridge Merino base layers have you covered. Plus they're odor resistant, making them perfect to pack for a trip since you can wear them again and again.
Aspect Midweight Base Layers
Our Aspect base layers are great for all the winter activities — resort skiing, ski touring, cross country skiing or snowmobiling. But they also keep you comfortable for winter running, summer camping and backpacking, and as a base layer for working, running errands or just hanging out at a home. For uphill activities and whenever you'll be breaking a sweat in cold weather, Aspect base layers are the way to go.
Inversion Heavyweight Base Layers
Our heavyweight Inversion base layers provide more warmth than our Aspect base layers without adding bulk. The sleek design is perfect for stormy resort days, sub-zero dog walks or snow shoveling days, or when you want soft, all natural Merino wool next to skin.
Even though our Inversion base layers are super warm, thanks to Merino wool's amazing properties, you're unlikely to overheat wearing them. Merino wool is naturally breathable, moisture-wicking and temperature-regulating. If you run cold or spend time in the cold, you'll love our Inversion base layers.
