Jasmine Silk’s thermal long johns offer a comfortable base layer to sit discreetly beneath your clothes. All the men’s long johns in this collection are made with natural silk fibres meaning they offer superb comfort and are incredibly soft on the skin. Silk naturally regulates body temperature meaning it will keep you cool in the summer and warm in the winter, and the breathability means there is no risk of overheating.
Choose from black, white or grey to find the perfect silk long johns to wear beneath your clothing. We have a wide selection of men’s undergarments available including silk tops and boxers.
