If you go on a winter sports holiday and want to dress well, it is best to start with the basics: thermal underwear. It is the first layer of your ski outfit and, above all, the one that keeps you warm in all conditions. An absolute necessity, high up on those snowy peaks. Thermal underwear sits close to your skin and ensures that the heat generated by your body is not lost. It also wicks away your sweat well, so you never feel clammy and cold. Combine this base layer with an insulating mid layer and waterproof outer layer for a smooth ski holiday!
