What’s the difference between waterproof fabric and sealed seams?

Waterproof: the fabric keeps water out. Fully sealed: the seams do too. Here, the CIMASHELL membrane has a 10,000 mm water column rating and the seams are sealed, so water gets through neither the fabric nor the stitching.

Does it meet ultra-trail mandatory kit requirements?

Yes. Its waterproof membrane and seams meet ultra-trail mandatory kit requirements. Check your race rules.

What should you wear underneath?

A breathable technical base layer. In cold weather or at night, add an insulating layer. The jacket protects against rain and wind; it does not provide warmth.

How should I care for them?

Machine wash at 30 °C with detergent for technical clothing. Use a gentle spin cycle and no fabric conditioner. To reactivate the water repellency, use a waterproofing spray or tumble dry on a low heat setting.

Is it available in larger sizes?

Yes. It comes in sizes XS to 2XL.

How does it differ from the STORM PRO?

The STORM PRO has a three-layer ULTRASHELL® membrane with a 20,000 mm water column rating (260 g in size S). The STORM is lighter at 185 g in size S, with a CIMASHELL membrane rated to 10,000 mm.

How many pockets does it have?

One zipped chest pocket. No side pockets.

What are the delivery times for this product?

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 in all weathers and won’t choose between low weight and protection: a jacket to take on every run without weighing down your pack.

What makes it different?

Our CIMASHELL technology combines waterproofing and breathability in a jacket weighing 185g in size S that packs into a trail vest.

How waterproof is it?

10'000 mm Schmerber waterproof rating, welded seams, water-repellent YKK Aquaguard® zips and a close-fitting hood.

How breathable is it?

It wicks away sweat at 12'500 g/m²/24h. Like any waterproof jacket, it can trap moisture during intense effort in the rain: run with the zip open; the fastening tab keeps the jacket in place.

This jacket slips into your running vest without a second thought and comes out without breaking stride. Waterproof, windproof and breathable, it does its job without getting in the way.

Built to match your stride, not fight it. The kind of jacket you pack out of instinct, never out of calculation.

In summary This content is written by AI

Customers particularly appreciate the build quality and very fine finishing, which several of them describe as excellent. They also praise its performance in bad weather: tested during rainy outings, heavy rain, and even a mix of snow and rain, it keeps them dry. Its cut is generally well designed and the colour is well liked. However, it can run small or feel tight around the waist, so check the sizing carefully; several customers also regret the lack of side pockets.

I usually wear a size M. This time I went for L to be able to wear a thermal sweater or fleece underneath. It's great. Light, good windproof and ultra-lightweight.
