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 should I wash this garment to preserve its breathability?

Wash at a maximum of 30°C. The golden rule for sportswear is to avoid fabric softener: it clogs the micro-pores of the fabric and blocks moisture wicking. Air drying is very quick — avoid the tumble dryer.

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 men who take part in winter activities and are looking for a thermal base layer combining comfort and softness: alpine skiing, snowshoe hiking, winter trekking. Ideal for those with sensitive skin who want a garment that feels invisible against the skin.

How should you wear it?

Wear as a base layer directly against the skin, under a fleece or ski jacket. The stretch fabric moves with you without riding up. For high-intensity activities, wear it alone; in extreme cold, add a lightweight fleece on top.

What makes the difference?

Its seamless knit construction fits the body like a second skin, with no friction points whatsoever. The bamboo and silk blend provides immediate softness and warmth from the very first contact.

Invisible. Comfortable. Everywhere.

A top that disappears on you. The seamless construction has no texture to rub against your skin — wear it all day without a thought for irritation. As discreet as a second skin, it insulates without weighing you down.

Bamboo and silk bring a rare softness to a technical base layer. Not the synthetic texture you put up with — the natural softness you choose.

And whether you are pushing hard or standing still, the stretch fabric adapts to your every move without ever holding you back — whether you are skiing, hiking or roping up.

- No protruding seams across the entire surface of the garment.

Integrated silk

I like the strech and soft feel in the material. I was expecting a bit thicker and warmer material, I think this will do fine until -10C with Cimalp Softshell ski trousers.

The STRATEGIC TOP 5 H is my go-to base layer for long bike rides. The L/XL size fits me perfectly (1.78 m, 80 kg). It fits my torso snugly without being too tight. The bamboo rayon used primarily in its construction is a wise choice.

Size maybe a touch large, but as I was between the two it fits me perfectly. (I'm 1.73 m and 68 kg, I took S/M.) The material is very pleasant. I don't know if it's normal, but I find it has an anti-odour side, which is great. Never had a wet feeling even during intense effort. I can only recommend it
