Once you have your base layer in place, it’s time to add your mid and outer layers. Often, the only mid-layer you will wear will be over your core and on your feet. Pullovers, hoodies, or sweaters made from fleece or wool make great mid-layers—even better if they have zip fronts, so you can ventilate and cool down if you get warmed up or while indoors. Heavy synthetic or wool socks over your liners will keep your feet warm and dry.
Lastly, you’ll need an outer layer. Over your core, choose a coat or jacket that’s insulated, as well as wind and water resistant. For your legs, regular pants over your base layer serve as an outer layer. When engaging in snow sports or on particularly cold days, however, you’ll probably want a mid-layer over your legs, like fleece pants or a pair of leggings, and then a pair of snow pants or bibs. Choose outer gloves or mittens that are wind and waterproof to wear over your liner gloves.
