For men who go winter hiking, snowshoeing or mountaineering in cold conditions, and who are looking for a natural, soft and warm first layer. Ideal for long outings where effort and rest alternate.

Worn next to the skin, directly against the body. Layer it first under a fleece or a softshell jacket. Its close-fitting cut eliminates unnecessary volume. Thumb loops keep it in place at the wrists under gloves.

Merino wool isn't just a warm fabric — it's a natural thermal regulator. This extra-warm top stands out for its soft touch without irritation and its ability to maintain stable warmth both at rest and during full effort, without becoming saturated with moisture.

Lifetime repair

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

Warmth from within

In extreme cold, the difference isn't made by outer insulation — it's made by the base layer. This merino wool top acts like a second skin that actively regulates body temperature: warm at rest, breathable on the move.

Where synthetic fibre forces a choice between warm and breathable, merino wool does both. It absorbs perspiration without chilling, releases moisture without leaving a wet feeling. No irritation, even worn directly against the skin all day.

Designed for long winter outings where conditions shift, this EXTRA-WARM top is the thermal foundation for demanding alpinists and hikers.

Lovely quality top, this is the 3rd one I have purchased I use them for work and they keep you dry and warm. The tailoring and attention to detail is really impressive.

Taille légèrement grand (1m83 78kg pour du M acheté), n'est pas moulant mais remplit parfaitement son rôle de sous-couche chaude. Sensation au toucher très agréable, et pas de mauvaises odeurs en effet !

Le S est parfait après retour du M qui était trop grand alors que je taille habituellement entre M et L (1m81, 77 kg tour de poitrine 104). Je pense donc qu'il faudrait revoir votre guide des tailles. Mais le produit est très bien !
