Discreet by nature, thermal baselayer is in fact the cornerstone of any winter outfit designed for extreme cold. Created to keep you warm in all circumstances, it must also deliver comfort in every situation. Fusalp men’s thermal underwear is crafted from fibres renowned for their insulating properties. Pleasant to wear, these pieces slip easily under a ski outfit or an urban look alike, offering warmth, breathability and complete freedom of movement. True to the Maison’s “fashion-tech” DNA, they unite alpine heritage with a contemporary couture spirit, helping you feel at ease in your clothes without ever compromising on style.
Premium Materials for Thermal Comfort.
Crafted from premium fibres, Fusalp men’s thermal underwear offers optimal protection against the cold. Cashmere, modal, polyamide, elastane and bi-stretch textiles are combined in unique compositions that deliver warmth, breathability, softness and durability. A noble material par excellence, cashmere is renowned for its insulating qualities and refinement, while modal lends suppleness and fluidity for a welcome sense of freedom. Bi-stretch fabrics ensure multidirectional elasticity thanks to a specific weave, allowing garments to move effortlessly with the body while retaining their shape over time. Some models also feature brushed Powerstretch® technology, an innovative textile that combines warmth and support. Soft against the skin, it locks in body heat while offering a shaping effect, ideal for demanding activities such as skiing or simply for everyday wear.
A good thermal layer should cocoon you in comfort while becoming instantly unnoticeable. Our tops and leggings made with Seamless technology are constructed in a single piece, without side seams. This eliminates friction and irritation, even during intense effort and repeated movement. The result is maximum comfort and unrestricted freedom, with garments that act like a second skin from morning through evening.
An ally for elevating style while maintaining comfort.
Attention to detail makes all the difference. Protective turtlenecks or minimalist crew necks, discreet zip fastenings, subtle textural contrasts and carefully placed logos give each garment a confident style statement. Many models are also available in several colours. Timeless black, pure white, seasonal tones and dynamic shades such as bright green allow you to vary combinations and personalise your look in every detail. Each piece is studied with care, whether you choose a slim, extra-slim or regular fit. Close to the body to maximise thermal performance and enhance layering, or looser for everyday ease, every model is designed with the same commitment to precision and always with elegance in mind. By uniting performance and aesthetics, Fusalp elevates men’s thermal underwear into true fashion creations.
True allies of layering, Fusalp thermal underwear is the essential base of every winter outfit. Traditionally worn beneath a jumper or trousers, they are equally effective under a light jacket or down jacket in milder weather. A thermal top can also be worn on its own indoors or in casual settings, balancing laid-back chic with absolute comfort.
Built to last, Fusalp thermal underwear retains all its technical qualities season after season. The selected fibres preserve their elasticity and performance through repeated washing. Each piece comes with precise care instructions to ensure long-lasting quality, maintaining the softness of cashmere, the resilience of bi-stretch fabrics and the effectiveness of Seamless technology.
More than just technical garments, these creations reflect the philosophy of Maison Fusalp: combining textile innovation with couture savoir-faire in a “fashion-tech” spirit, offering the modern man pieces that are both functional and desirable. Thermal leggings and tops become essential allies of the masculine wardrobe, uniting elegance, performance and freedom of movement.
