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 women who ski, go hiking or take part in other winter activities in cold conditions and are looking for a lightweight, comfortable and effective base layer. Ideal for all light to moderate activities.

How should you wear it?

Worn directly against the skin as a base layer, under a fleece or a ski jacket. The round neck stays discreet and does not interfere under a neck gaiter. The feminine cut fits perfectly without creating volume.

What makes the difference?

Ultra-lightweight and versatile, this women's crew-neck base layer is the foundation for active winter days. Balanced thermal insulation, soft and breathable fabric — comfortable in both moderate activity and dynamic conditions.

The base layer you stop noticing

A great base layer is one you forget the moment you put it on. This women's thermal crew-neck top does exactly that: soft fabric against the skin, a fitted cut that follows without restricting, balanced insulation for active days.

Unlike base layers that overheat and saturate under effort, this WARM top breathes and continuously wicks away perspiration. You stay dry and at the right temperature, without having to undress. Comfort that keeps up with your pace.

The understated crew neck doesn't interfere under a neck gaiter or helmet, and the feminine cut stays invisible under a fleece. A simple, effective piece that belongs in every winter kit.

In summary This content is written by AI

Customers especially appreciate its warmth, softness and comfort: many find it pleasant to wear, warm and well cut, while several consider the fit perfect or true to size. It is used in particular for hiking, and one customer is already on their fourth purchase. Sizing feedback is nevertheless mixed: some find it large, while another finds it a little tight, so check the size carefully before choosing.
