The Giordana Ceramic Long-Sleeve Baselayer is the versatile all-season baselayer we have been looking for. In the summer, its Resistex Bioceramic microfiber construction reflects the hot rays of the sun to lower the surface temperature, while using its insulating properties in the winter to keep our body temperature regulated. Its form-fitting design contours the body with a four-panel construction to ensure the benefits of the Bioceramic technology are received.
