Thermal base layer delivers warmth and comfort in every condition, whether enjoying an unforgettable day on the ski slopes or spending long hours outdoors in the depths of winter. Essential to any cold-weather wardrobe, Fusalp women’s thermal layers combine technical performance, elegance and comfort to support you through the season’s coldest months. Designed as a second skin, they slip effortlessly beneath sports or city outfits to shield against low temperatures. Leggings and tops form an indispensable duo, blending warmth, breathability and freedom of movement, true to Fusalp’s “fashion-tech” DNA where alpine heritage meets contemporary couture, ensuring you always feel at ease and always in style.
Premium Materials for Thermal Comfort
Our women’s thermal baselayer is crafted from the finest fibres to deliver maximum comfort in cold weather. We combine natural and synthetic textiles with proven properties to ensure warmth whatever the conditions. Cashmere, modal, polyamide, elastane and bi-stretch fibres provide heat, breathability, softness, durability and flexibility for an unrivalled sense of well-being. Cashmere is valued for its thermal qualities and delicate touch, while modal lends suppleness and fluidity. Bi-stretch fabrics ensure multidirectional elasticity thanks to a specific weave, giving garments that move with your body while retaining their shape over time. Some models also feature brushed Powerstretch® technology, an innovative material that combines thermal comfort with a supportive effect, ideal for retaining body heat and ensuring an optimal fit in any situation.
A thermal layer should feel like a second skin. With Seamless technology, we create tops and leggings made in one piece, without side seams. This eliminates irritation caused by friction, even during intense sport, while guaranteeing maximum comfort in a garment that follows every movement whether on the slopes or in the city.
Every piece is designed to move fluidly with you. Our women’s thermal underwear comes in a variety of fits, from slim and extra-slim to regular, to suit all body types and uses. Close-fitting cuts maximise warmth and technical efficiency, while slightly looser fits prioritise everyday comfort. Each model is designed with precision and never compromises on style.
Finishing touches elevate the collection to excellence. Protective turtlenecks or minimalist crew necks, invisible zips or contrasting logos, every detail is carefully considered so that your thermal underwear remains a stylish piece you wear with pride. Some designs are available in multiple colours, enriching the collection with versatile pairing options. Timeless black, pure white, seasonal tones and vibrant shades such as bright green give each garment its own identity, ensuring that technical performance never comes at the expense of aesthetics.
True allies of layering, Fusalp thermal underwear forms the ideal first layer of a winter outfit. Worn beneath a jumper or directly under a light jacket or down jacket depending on the season and weather, these technical garments are indispensable companions for successful days on the slopes. With their clean, refined aesthetic, they can also be worn on their own, whether indoors or in more relaxed settings.
Comfortable and stylish thermal base layers.
Designed to last, Fusalp thermal underwear will accompany you for many seasons. The fibres retain their softness, elasticity and thermal performance wash after wash. Each piece comes with precise care instructions to preserve the delicacy of cashmere, the stretch of bi-stretch fabrics and the effectiveness of Seamless technology. By choosing these garments, you are investing in durable technical underwear created to keep you warm and comfortable throughout your winter adventures.
More than simple technical layers, each creation embodies the Fusalp philosophy: fashion in the service of performance and performance in the service of style. Thermal tops and leggings become desirable pieces, expressing a couture vision of garments that are, at their core, functional. They celebrate the beauty of the body in motion, protected and enhanced by innovative fabrics and precise lines.
