Perfect for conditions year-round, the Capiline 2 long underwear from Patagonia are an incredible deal. Patagonia slaps a lifetime warranty on these babies, but you probably won’t need to use it because the fabric is durable (keep it away from flying embers, though) and will keep you warm even when you’re wet. Try the zip-neck for the option of wearing it as a ventilating v-neck or a bundled up turtleneck.
