As the lightest base layer in Giordana's line, the FR-C Pro Tank Base Layer actively pulls perspiration off your body to promote a pleasantly cool, dry feel. Lightweight microfiber fabric not only wicks moisture, but it maintains a lovingly soft feel as it sits flush against your skin. Giordana claims it weighs a mere 65 grams, meaning it won't weigh you down with excess bulk. And like all of Giordana's premium apparel, it's made in Italy with the utmost attention to detail.
