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 mountaineers and hikers who want a lightweight merino base layer with the temperature management of a half-zip.

For outings where intensity varies frequently: fast ascent, col stop, descent on crampons.

How should you wear it?

Worn as a base layer next to skin, under a fleece or a hardshell jacket. Open the zip on the way up to ventilate, close it at the summit to retain warmth.

What makes the difference?

Its half-zip at the collar allows instant ventilation when overheating on the ascent. The merino wool 150 g/m² delivers gentle warmth and natural odour-resistant properties over several days.

The climb, without overheating.

In the mountains, effort generates heat quickly. Wearing a sealed top means sweating, cooling down, sweating again.

This lightweight, regulating merino top responds to changes in intensity. The half-zip ventilates when effort ramps up; the wool retains warmth when the pace drops. The fibres neutralise odours over several days.

Because a good base layer adapts to the terrain, not the other way around.

Quick opening to ventilate during effort or protect the neck.

Very good product, but, and this is just a suggestion, why not offer your items in general with colors a little different than blue, black, and grey. In any case, the technical quality of your products is excellent.
