Which version should I choose: 150, 200 or 240?

The higher the fabric weight, the warmer the top. The 150 offers lightweight warmth for sustained activity in cool weather; the 200 offers balanced warmth for skiing and winter hiking; the 240 offers high warmth for the coldest days. In very cold weather, add a fleece over whichever version you choose.

Which size should I choose?

Choose your usual size and check it against the size guide on the product page. The fit is close to the body, like a second skin; some very tall customers find the sleeves a little short.

What should I wear over this top?

Wear it next to your skin as a base layer: a cotton t-shirt underneath traps moisture and leaves you cold when you stop. In cold weather, add a fleece, then a waterproof or windproof jacket to protect against rain and wind.

The merino yarn is fine (19,5 µm) and designed not to itch. A few customers who are particularly sensitive to wool do report a slight prickling sensation, though: try wearing it for a few hours first.

How many days can I wear it without washing it?

Wool limits odours, so you can wear this top on several outings before washing it. It still needs washing: how many days you can wear it depends on your level of effort and the temperature.

Can this top be machine washed?

Yes. Wash it inside out on a delicate or wool cycle at no more than 30 °C and 500 rpm, using a quality detergent and no fabric softener. Do not tumble dry, as it may shrink. Lay it flat to dry, away from direct sunlight.

Garment construction, weaving or knitting, dyeing and printing are carried out in China.

Are the bottoms shown in the photos included?

No: this top is sold separately. The bottoms worn in the photos are a separate item.

What are the delivery times for this product?

All orders placed by midnight are prepared the next day. In France, orders placed before 1 pm (excluding weekends) with Chronopost 24h are dispatched the same day. Delivery then depends on the carrier and takes 1 to 4 days in France. Delivery times for Europe and the rest of the world vary by destination.

Can I return the item if the size doesn't fit?

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.

Who did we design it for?

For skiers, hikers and mountaineers heading out in very cold weather who prefer the softness of wool to the feel of synthetic fabrics.

How warm are they?

High warmth: the warmest of the three versions. Worn under a fleece, this top retains body heat during long stops on the coldest winter days.

What is it made of?

Our CIMAWOOL technology: 50% merino wool (19,5 µm) and 50% polyester. The wool regulates temperature, while the polyester helps the fabric hold its shape.

What makes it different?

Fine merino yarn (19,5 µm) blended with polyester: the fabric retains warmth, wicks away moisture during activity and limits odours from one outing to the next.

When the cold sets in

A long stop, a freezing morning setting off from the mountain hut: in cold weather, your base layer can make or break the rest of the day.

This top in thick merino wool keeps warmth next to your skin without weighing you down. It wicks away moisture during exertion, while the wool limits odours, so you can wear it on several outings before washing it.

In extreme cold, add a fleece over it.

Because protection from the cold starts next to your skin.

In summary This content is written by AI

Customers especially appreciate its warmth, which protects effectively against the cold without feeling stifling. Many highlight its great comfort, “second-skin” feel and light weight, to the point of wearing it every day. It works equally well for motorcycling, winter Nordic walking and long hikes; one customer tested it successfully in winds of 90 km/h. Its quality and value for money are also praised. It does run a little small, so take one size up if you are between sizes.
