Consider a pair of tweed trousers a cold weather alternative to your favorite chinos. Warm and durable, tweed started out as all-weather hunting gear. There's a fuzzy logic to that signature heathered coloring (obtained by twisting different colored wool threads into a multi-ply yarn). It offered a camouflage for hunters back in the day, and now it simply adds a richness and depth to the fabric, which makes for the perfect pair of winter pants. Meaning they always look great—whether you're sporting boots and trudging through the snow on the weekend or kitted out in a shirt, tie and freshly shined lace-ups.
