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 women looking for a lightweight merino base-layer legging for hiking or skiing. For days of sustained effort where heat needs to stay balanced without causing overheating.

How should you wear it?

Worn next to skin, under hiking trousers or ski trousers. Its 150 g/m² weight is ideal for active days where breathability takes priority over maximum insulation.

What makes the difference?

WARM merino boxer briefs at 150 g/m²: regulated natural warmth, lightweight under trousers, naturally odour-resistant. Merino wool manages moisture during exertion without ever clinging to the skin.

Wool, but make it sport

Merino wool has everything it takes to be the ideal base-layer fabric — except it sometimes lacked the durability serious sportswomen demand. This thermal tight solves the problem by marrying natural fibres with technical ones. Balanced warmth, technical durability.

Worn directly under ski or hiking trousers, it stays invisible and in place all day. No riding up, no uncomfortable compression. The elasticated waistband adapts without digging in, with thighs and calves perfectly wrapped. Zero friction against the skin.

For women who want the natural comfort of wool without its drawbacks: the essential base for your mountain outings.

Key features

Natural warmth and thermal regulation for durable comfort in the mountains.

Tailored fit

Close-fitting cut designed to be worn under ski or hiking trousers. No extra volume, no visible bunching under the trousers.

Comfortable elastic belt

Flexible elasticated belt that keeps the boxer shorts in place under the trousers.

Warm and soft to the touch, enveloping without being too tight. I usually wear a size M, but based on the reviews, I went for a size S which is slightly loose. I'm 1.65 m tall and weigh 58 kg. I think that to get a fitted pant (like leggings) I should go for an XS, since the fabric is stretchy.

It's an order made by my sister, so I haven't received any feedback yet! But since I already have a top, I believe the quality should still be there! Wishing you continued success.
