Marin Lightweight Hooded Jacket

The Marin, for the days that can't make up their minds — cool at nine, breezy by noon, and you still have somewhere to be. Wind- and water-resistant lightweight nylon, gold or silver-tone zip and snap hardware, a drawstring waist that actually shapes the jacket, and a cotton plaid lining that shows at the collar whether the hood is up or down.

Roll the sleeves, zip it over a chambray shirt, and let the chest flap pocket handle the small things. Packable enough for a weekend bag, handsome enough to reach for every time the forecast looks uncertain.
