Which size should I choose?

Choose your usual size: this top fits true to size, but its cut is close-fitting and some customers find it snug. Size up if you prefer more room. The size guide on the product page gives body height and weight for each size.

What should you wear underneath and over it?

Underneath, wear a breathable technical base layer in synthetic fibres or merino wool. Add a trail jacket or running vest over it when the wind picks up or it gets cold.

Can it be worn in winter?

Yes, as a mid-layer over a technical base layer and under a jacket. Worn on its own, it is better suited to cool spring and autumn days.

Does it meet the mandatory kit requirements for an ultra-trail?

Yes: with its long sleeves and 180 g weight in size S, it meets ultra-trail mandatory kit requirements.

Does it protect against rain?

No, it isn’t waterproof: it’s a second layer that retains warmth while letting moisture from exertion escape. Add a waterproof jacket over it in heavy rain or cold wind.

What is it made from?

Made from 89% polyester and 11% elastane in a lightweight 150 g/m² fabric, giving it its stretch.

Does it have a pocket?

No, it doesn’t have a pocket for a phone or keys. Keep them in a running vest or belt.

How should I care for them?

Machine wash at 30 °C, preferably inside out, then air dry. Avoid tumble drying.

What are the delivery times for this product?

All orders placed by midnight are prepared the next day. In France, orders placed before 1 pm (excluding weekends) with Chronopost 24h are dispatched the same day. Delivery then depends on the carrier and takes 1 to 4 days in France. Delivery times for Europe and the rest of the world vary by destination.

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 run trails or hike in cool weather and want a lightweight second layer that adapts as their effort changes on the trail.

How warm is it?

A lightweight 150 g/m² fabric designed for spring and autumn: it keeps you warm at the start in cool weather and releases heat as you work harder. In winter, wear it as a second layer.

How breathable is it?

Highly breathable: the lightweight fabric lets moisture escape as you work, while opening the half-zip helps release heat on climbs.

What makes it different?

Our CIMAFLEX technology: a breathable stretch fabric, with a half-zip and high collar to regulate warmth. Meets ultra-trail mandatory kit requirements.

The second layer you’ll barely notice

When a trail starts in the cold, every layer counts. Too heavy and it slows you down. Not breathable enough and it soaks through. Between climbs and windy ridges, regulation has to be immediate.

This top is designed to adapt to changes in intensity. It provides warmth over the first few cool kilometres, then releases excess heat as you pick up the pace. Its stretch construction moves with you. Under a pack or running vest, you’ll barely notice it.

It meets ultra-trail mandatory kit requirements and a simple standard: protection without bulk.

Because on long races, every gram counts. And a second layer should feel like it’s barely there.

In summary This content is written by AI

Customers love this top for its comfort, lightness and warmth, making it pleasant to wear every day or while travelling. Several have worn it hiking in the mountains, from early morning or in autumn, and plan to use it for winter running or yoga. They also appreciate its breathability, fresh feel, quick drying and lack of odour during exercise. Several find the fit a little tight or too fitted, so if you prefer more room, choose one size up.

A very pleasant, lightweight fabric that protects against the cold. Ideal for hiking this April, starting in the morning. I wear a small for jackets and a medium for tank tops because I don't want them to be too fitted. I highly recommend this top; it's very well-designed and so comfortable! Never disappointed by the quality of Cimalp products.

This little top is very comfortable to wear in the fall. I used it for hiking in the mountains. It's very breathable. The color is lovely. I think it would also be great for yoga. It would be even better if it had a pocket for your phone and keys.
