For winter sports enthusiasts who push hard — ski touring, winter trail, mountaineering — and refuse chafing during effort. Ideal for those who move a lot and want a base layer that disappears against the skin.

Worn next to skin, directly against the body. Layer it as a base layer under your fleece or ski jacket. Its fitted cut hugs the torso without adding volume: it stays discreet under any mid-layer.

Designed for athletes who make no compromises, this thermal top stands out for its seamless construction and its ultra-fitted stretch cut. Result: zero chafing, zero irritation, even after hours of intense effort.

Lifetime repair

A repaired garment is a story extended. We ensure the longevity of your Cimalp equipment, season after season.

When the seam disappears, the body takes over

In winter mountain conditions, every detail counts. A crease, a poorly placed seam, a fabric that pulls at the wrong moment — and concentration goes out the window. This thermal top meets that demand with a seamless knit construction, seam-free from collar to cuffs. The fabric glides, moulds, follows.

The stretch cut follows the male physique without ever restricting shoulders or arms. Reach up, bend down, pivot: the top stays in place, invisible under layers. Absolute comfort even after hours of effort.

Lightweight and thermoregulating, it maintains active warmth during intense ascents and stays dry when the body heats up. A discreet but essential ally for long winter outings.

Testé ce matin par temps froid et pluvieux, enfilé sous la veste Cimalp Storm Pro. La taille de ce sous vêtement thermique est très ajustée mais confortable. La qualité isolante est remarquable, moi qui suis sujet à une transpiration excessive durant l'effort, je n'ai ressenti aucune sensation de froid ni d'humidité importante qu'on peut ressentir avec un tee-shirt en coton. C'est un très bon produit.

Pris dans la plus petite taille car pour une femme (les couleurs étaient plus sympas que les modèles femmes). Seconde peau très agréable, efficace en course à pied avec juste un petit coupe vent par températures négatives. On ne sent pas qu’on transpire et on garde la chaleur sans mourrir de chaud pour autant : vraiment un bon produit. Très moulant, long sur les hanches, mais très souple. Matière sur les épaules très confortable et souple.
