Ideal for cool-weather starts, slip the Seirus Thermax skull liner beneath your helmet or pack it as a minimalist beanie for light and fast adventures. Ultra-thin Thermax(R) polyester with a bit of Lycra(R) spandex stretches to fit, wicks away moisture and dries quickly to keep you warm. Flatseam construction and 4-way stretch improves comfort.
