Here's what other sites are saying:
Designed to be worn under any helment, the REI Performance Headliner combines a balaclava and neck gaiter to keep your head, neck and face warm. Trim-fitting, split-face design provides convenient coverage options-keep your face covered or not; either way, the head cover stays in place. Polyester is blended with spandex for form-fitting stretch; fabric wicks moisture away from your body for quick evaporation. Smooth exterior is soft on the inside for comfort next to skin. Overstock.
