Giordana Wool Base layers are lightweight, wool undergarments made to deliver all the benefits of this natural fiber. The Mimosa™ fabric, a blend of Merino wool, nylon and spandex with Merino wool being the biggest component, delivers the unique qualities that no other material can duplicate; highly breathable and moisture moving with superior insulation properties, even when wet. Constructed from four panels to contour to the body comfortably under jerseys and jackets, the small bit of spandex in the base layer's mix helps create a more fitting garment allowing the benefits of the Merino wool to be fully realized.
