Do you feel that? The slight crispness in the morning air? The cool breezes that rustle the first batch of fallen leaves? Sweata weatha is here. And we're here for it. Bring on the change, bring on the sleeves. During this time between the last stretches of summer and the short, dark days of winter, a lightweight sweater can come in clutch. Why? Because they have everything you want and nothing you don't.

Seemingly engineered to insulate you from the chill without overheating you when the sun is shining, this particular breed of sweater is made from cotton and finer wools with a blend of synthetics—knit and woven in patterns to promote air circulation. Like a well-tinted moonroof on a luxury car, these offer just enough coverage to keep you cool when it's hot out and cozy when there's a chill in the air—all while looking damn good. Wear them on their own now and then layer them over a shirt and under a jacket when the temperature really starts to dip. We've pulled a dozen of our current favorites, in a range of prices.
