Can I wear a cotton t-shirt underneath?

This is strongly inadvisable. Cotton retains moisture and dries very slowly, leaving you feeling cold during rest stops. Wear this technical garment directly against your skin.

What should I wear over this garment?

This model is designed to act as a second skin. Its role is to wick away moisture and keep you dry. If it's cold, add a fleece on top (second layer). To protect yourself from the elements, wear a waterproof jacket as your third layer.

How do I wash and dry my merino wool garment?

Wash inside out on a delicate or wool cycle (max 30°C and 500 rpm), using a quality detergent and no fabric softener. Avoid the tumble dryer to prevent shrinkage. Leave to dry flat naturally, away from direct sunlight.

What are the delivery times for this product?

If you place your order before 1 pm (excluding weekends), it will be dispatched the same day. Allow 2 to 4 working days for home delivery or collection point delivery within mainland France.

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 active men in the mountains looking for a versatile base layer: ski touring, alpine skiing, winter hiking or high-altitude trekking. Ideal for those who alternate between effort and rest, and appreciate a natural material that adapts to varying intensity levels.

How should you wear it?

Wear it as a base layer next to the skin, directly under a fleece or a ski jacket. The half-zip lets you regulate heat without having to remove your outer layers. For mixed activities, wear it alone at the start of your effort, then add an insulating layer when you stop.

What makes the difference?

Its merino wool naturally regulates heat while keeping odours in check, even with intensive use. The half-zip allows you toadjust ventilation during effort to stay dry all day.

Naturally warm, naturally you

A top that breathes at the rhythm of your effort. Merino wool regulates your temperature without ever overheating, absorbing moisture to keep you dry. Soft against the skin from the first wear, without irritation even worn next to skin.

The half-zip opens in one move to ventilate on the descent, closing instantly to retain warmth at a stop. No compromise between comfort and performance.

And when the day stretches beyond the summit, the wool naturally resists odours — you head back to the hut without needing to change.

In summary This content is written by AI

Customers love the comfort of this base layer, describing it as very pleasant to wear, even during activity. Many find it warm yet thin, making it ideal as a first layer in cold weather, while several praise its quality. After three outings over three days, one customer found it still comfortable and odour-free; another has already bought a second one. However, take care when choosing the fit: it can be very close-fitting, and the length may not suit people between sizes or with longer torsos.
