Best Base Layers for Men

On cold winter days, extra layers are a must. But if you plan to hike, ski, climb or hit the gym, having a thin layer that keeps you warm without hindering your movement is crucial to performance. That’s where a base layer comes in. Typically worn next to the skin, it helps regulate core body temperature and prevent moisture buildup. You’ll want to stay away from cotton styles and instead opt for ones made of polyester, which are naturally much more breathable, sweat-wicking and durable. Below, we’ve rounded up our favorite base layer sets for men on the market.
