With a slim fit and clean look, we like the Kari Traa Eva Down Jacket as a cold-weather layering piece or a stand-alone down sweater. The 80/20 down is light but warm, keeping us insulated without the bulk of old-school insulation. The stretch fabric panels and triangular baffles have a slimming effect, too, so we can look trim and layer it easily under a shell in wet and windy weather.
