Think of this as a silky baselayer with a smidge of protection against wind and chill—and a lot of protection against sweat. The lightweight, stretchy fabric is neither waterproof nor windproof, but it maximizes moisture release: The brushed, polyester lining wicks and dries fast. “Sometimes I wore it next-to-skin because it minimizes clamminess so well,” says a tester. Note: The thin, satiny fabric isn’t intended for abrasive punishment.
Fit & features
The sleek, body-hugging cut accommodates a light baselayer, but nothing bulkier, and it works well under other layers. Four-way stretch and articulated seaming through the arms allow for unlimited movement. And the high-collared, close-fitting hood serves as a balaclava that kept skiers cozy in 20°F temperatures.
