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?

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.

The perfect balance between warmth and breathability

Too light, you're shivering at a standstill. Too heavy, you're overheating on the move. Your base layer needs to handle both.

This merino top actively regulates your body heat, wicks moisture in the mountains and maintains its performance over multiple days out. Its wool neutralises odours naturally.

Because a good merino top needs to perform as well on the move as at the rest stop.

In summary This content is written by AI

Customers love how warm it is despite its thin construction: it comfortably lasts through a full day of skiing, can be worn for several days and also works well as a base layer for everyday use or work. Many appreciate its comfort, accurate fit and pleasant fabric. They also praise its temperature regulation: moisture is efficiently wicked away, with no feeling of cold or odour after hiking. Choose the weight according to your activity, though: some find it too warm for Madeira, while others would have preferred something warmer.

Highly recommended as a first layer on extremely cold days. It maintains the feeling of warmth even when you stop, unlike normal thermals.

Perfect for a full day of skiing. I even wear it for 2 or 3 days. I'm waiting to be able to use it for glacier hiking and snowshoeing. But I think it'll be great! Well done, in any case. I also use a Guide Pro jacket. This is my second one after the first one lasted almost 10 years.

The use for mountain biking is excellent, as it allows for fewer layers. A top-notch product. I recommend it.
