PATAGONIA MICRO PUFF STORM

The warmest and most waterproof of the trio, the Micro Puff Storm uses Patagonia’s proprietary and ultralight waterproof H2NO waterproof-breathable membrane on the outside and its down-mimicking PlumaFill inside. Originally designed as a climbing belay jacket, its features are just as useful on skis: generous hood, mini-snow skirt, two big hand pockets and two huge interior mesh pockets, ideal for gloves or skins. The only thing we don’t love is the boxy cut, but it does layer over anything. 615 grams. $625; patagonia.com
