The technique always

Water repellent


- 2 large zipped hand pockets on the front compatible with a harness and a backpack - you can slip in an IGN TOP25 card without having to fold it.

- 2 vents under the arms for ventilation in the event of sustained effort (always appreciable... Even essential).

- 1 YKK© Vislon© 3mm ventral zip with two sliders (bottom or top opening)

- Drawstring at the waist and Velcro wrist tightening

- Large helmet hood. 3-point tightening at the collarbones and at the back of the head. No holes or eyelets on the hood: the tightening mechanisms do not create an entry point for water, snow or wind

- Storm flap inside the belly zip - you'll thank us for it.

- Protection on the chin and cheeks

- Seams sealed with heat-sealed strips

- YKK© Aquaguard Coil© 3mm hydrophobic zippers

- High UV-resistant color dye, so you don't have a faded jacket after a few seasons.

- Waterproofing 20,000 Schmerber

- Weight: 480gr


We recognize the TETRAS jacket by:

- its close-fitting cut, a little longer at the back so you can bend down without revealing your back. The sleeves are a little longer so that the wrists remain well covered when you raise your arms. A very refined style and therefore timeless.

- its material is both recycled and recyclable, water-repellent and guaranteed to be free of endocrine disruptors. We too prefer virtuous textiles for the planet and our health.

- its versatility: this technical jacket is suitable for all seasons and (almost) all activities: ski touring, trekking, summer mountaineering.

- its superpowers: 100% waterproof (20K), windproof and breathable. It is perfectly light, as comfortable in the mountains as on a bike, in the wind, the rain or the cold. Woven and dyed in France (Ardèche), assembled in the EU.

Système de couche

Did you know ? The ptarmigan - our totem animal - changes its plumage depending on the seasons. It turns white in winter to escape predators and increases the fluffiness of its feathers to avoid cold snaps.

The TETRAS jacket is inspired by this: it plays the role of the last layer, the one that protects from wind and rain, without sacrificing breathability... And therefore comfort.

To enjoy your favorite activity whatever the weather, here's the basics: layers.

1- The first layer, called internal, must be breathable, to guide perspiration towards the outside of the garment.

2- The intermediate layer is insulating, it helps retain heat.

3- the outer layer protects from bad weather: waterproof, breathable, windproof. It is to this last category that the Tetras belongs.

By building your outfit based on this system, you gain comfort and versatility. During exercise, you can remove the intermediate layer and then put it back on. In short, multi-layering is the basis.


We often like to say that we make our mountain clothing with you. Since the creation of Lagoped, we have constantly exchanged with professionals and enthusiasts to improve each piece. To equip yourself as well as possible, always with sustainability in mind. This is how our clothes are made:

- Lagoped fabric is made up of 3 different layers that are only a few millimeters thick when assembled.

- The outer thread is Italian (from recycled plastic bottles), the weaving and dyeing are done in Ardèche.

- The membrane is a polyester made in Europe from scraps of recycled membranes (pre-consumer).

- The inner layer is a very very fine Italian knit, made from recycled yarn.

The three layers are combined in Austria, before assembling the jacket in Poland. Which makes it a European product - a small feat for such a technical garment.

Économie circulaire

- Polyether-ester harmless to health

- Free from perfluorocarbons

- Fully recyclable laminates

- Fully recyclable top and supports


- 3-layer fabric 100% recycled Polyester (r-PET)

- Polyurethane (PU) sealing strip


The TETRAS jacket can be machine washed inside out, with the zips closed at 30°, regular detergent (not too much, and eco-friendly is a plus) and without softener.

She prefers gentle spinning and abundant rinsing. Once the garment has air dried on a hanger, you can put it in the dryer for 10-15 minutes (but no more) by choosing a synthetic program. This will reactivate the water-repellent treatment which is initially applied by coating and polymerization, and therefore by heating it.

Unfortunately, water repellency does not last forever and fades over time. Use specific PFC-free sprays to reactivate it.
