What is a sleeveless insulated jacket for?

It keeps your core warm while leaving your arms free. Wear it on its own in cool weather or under a waterproof jacket when it gets colder.

Is it warm enough for winter?

It keeps your core warm in cold weather. In very cold conditions, wear it under a jacket or add a warm layer underneath.

It’s water-repellent, not waterproof: its DWR treatment sheds water droplets, and its insulation retains warmth even when damp. In heavy rain, wear it under a waterproof jacket.

How should you wear it?

Wear it as a mid-layer under a waterproof jacket for extra warmth when hiking, or as an outer layer on cool days in town.

Yes. It packs completely into its compression sack and fits in your rucksack.

Which size should I choose?

It runs slightly small. If you're between sizes, choose the larger size.

How do I wash my synthetic down jacket and restore its loft?

Wash at 30°C with a specialist down detergent (no fabric softener) and a gentle spin cycle (600 rpm). Add wash balls or tennis balls to the drum to help redistribute the fill. Dry on a hanger in the open air or in the tumble dryer with the balls, and pat it down to distribute the fibre evenly.

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 hikers who want a warm sleeveless layer to wear on its own in cool weather or under a jacket, with arms free to move.

Arms free, core warm

On an uphill trail, your arms warm up long before your core. A sleeveless layer keeps your core warm without restricting your movement.

This sleeveless insulated jacket keeps you warm even when it gets damp, leaving your arms completely free. Its high collar protects your neck, while the close-fitting women’s cut follows your shape.

Wear it on its own in cool weather or under a jacket when the cold sets in, then pack it into its compression sack.

Because your arms can be warm while your core is cold.

In summary This content is written by AI

Customers are won over by its remarkable warmth despite its slim, lightweight design: many find it very warm, comfortable and pleasant to wear. It works well for winter hiking, on foot or with snowshoes, for everyday wear and as an excellent mid-layer. Several customers also appreciate how easily it compresses and takes up little room in a pack, along with its attractive cut and neat finishes. However, it can run small or feel tight under the arms and across the chest, so consider sizing up.

Beautiful and very warm down jacket. I went up a size from my usual because I like to have room to move when hiking and to wear it potentially with a fleece underneath. The length is perfect.

I was surprised by how warm it was, considering its thinness and how little space this down jacket takes up when compressed. It's very warm and comfortable for hiking in winter weather, whether on foot or snowshoes. It's also perfect for everyday wear when temperatures are milder. Lightweight, easy to pack, and ideal as a mid-layer.

I had to exchange my down jacket from XL to 2XL. The exchange was carried out quite quickly. Good product, compressible and warm.

Je l’avais pris en taille M, je le garde, mais il ne faut rien porter dessous, taille un peu petit pour moi , je l’ai donc commandé en taille L, parfait. Les deux me seront utiles. Très agréable à porter et bien chaud.

Beautiful sleeveless down jacket. Elegant and warm. Lovely finish. I hesitated between two sizes, but it was ultimately a little too big for me. I had to order a size down.
