EVEN ON ORDINARY DAYS YOU CAN WEAR EXTRAORDINARY SHIRTS. Wear the X-BIONIC® Buddyguard directly on the skin. The extra soft, temperature-regulating Skin NODOR® cools when it‘s warm and warms when it‘s cold. The Buddyguard is a reliable companion, regulating the body temperature perfectly whether going from office to sport to a party. Silver ions are effectively used to prevent odours. And after washing, the shirt dries quickly.
