Who did we design it for?

For trail runners who run in all conditions and refuse to choose between weight savings and protection from the elements.

For those preparing a mandatory-kit race who need a jacket that ticks the box without weighing down the pack.

For those who want a discreet, no-nonsense trail jacket — the one you always pack and never regret bringing.

For those who need to run freely on mountain trails, even in the rain.

How to wear it?

Fitted trail cut, designed to be worn directly over a base layer. Stick to your usual size; the pre-shaped cut is engineered for full arm mobility.

The retaining toggle lets you run with the jacket open without it coming off, so you can vent as the effort ramps up.

What makes it different?

Its CIMASHELL membrane blocks rain at 10,000 Schmerber and breathes at 12,500 MVP, with sealed seams, in a stretch fabric that moves with every stride like a second skin. The standard accepted for mandatory kit at ultra races like UTMB. Light enough to forget you're wearing it, tough enough to go the distance.

The lightweight protection you forget you're wearing

On the trail, the rain never warns you. It hits on the climb, it hits on the technical descent — and the jacket you didn't bring becomes the only thing that matters.

STORM slips into your vest without a second thought, and comes out without breaking stride. Waterproof, windproof, breathable — it does the job and stays out of the way.

Built to follow your stride, not fight it. The kind of jacket you grab out of habit, never out of calculation.

At 1.82m tall, I ordered a size L and it fits me perfectly, allowing for easy movement. It's not too tight, except perhaps a little more at the bottom for support. I tested it in light rain: no problem, and the hood stays securely on my head. It would also be ideal for summer hiking as a windbreaker. As for breathability: it always depends on what you wear underneath, and I haven't tested it in cold weather, but given the material, it should live up to its promise. And it has a beautiful design. I'm sold!

Perfect size, excellent quality, tested for waterproofing on a very rainy 40km trail run without any problems. It's the perfect waterproof jacket, and especially at an affordable price.

Fits well and the cut is pretty good. I went one size up from my usual size to get the right sleeve length. Otherwise, it perfectly replaces my old jacket from a competitor brand, at a lower cost.

I am quite pleased with the product. It is slightly tight under the armpits, but it's manageable. I used it for mountain trail running, and it provides just the right insulation when the temperature is close to zero with wind. Two additional pockets would be a plus.

A run in 3-degree weather, and I didn't feel cold at all, quite the opposite, despite wearing a very thin long-sleeved t-shirt underneath. It cuts out the wind perfectly; I was even warm towards the end of my run, despite a slow pace and not pushing myself too hard. This product perfectly meets my expectations.
