GRAND TETRAS: the 3/4-length jacket designed for mountaineering in bad weather

On a mountaineering route, protection often comes down to a few extra centimeters of fabric. GRAND TETRAS's 3/4-length cut covers the hips and upper thighs—a length that makes all the difference when wind drives snow horizontally across a ridge or while waiting at a belay.

Complete protection from rain, snow, and wind

The jacket combines 20,000 mm waterproofing, a RET breathability rating below 13, and windproof construction. In other words, it withstands a prolonged downpour without letting water in while wicking away the vapor produced during a sustained climb, where a standard waterproof shell would eventually feel clammy.

630 grams for a jacket with this much coverage

At 630 g, GRAND TETRAS remains lightweight given its length and level of protection. It packs down into your bag on days when the weather holds, and comes out as soon as the skies turn threatening. Its water-repellent treatment is formulated without PFAS: water beads on the surface without relying on fluorinated compounds.

The garment in detail

coupe 3/4

S'arrête au-dessus du genou pour rester libre en montée, sans jamais alourdir la démarche au porté.

2 poches repose-main

Les mains s'y glissent à plat pour se réchauffer en marchant, sans jamais serrer au poignet ni à la paume.

poche intérieure zippée

Se referme complètement, retient les objets même tête en bas ou lors d'une chute en pleine montagne.

capuche casque 3 points

Se resserre d'un geste sans réduire le champ de vision une fois ajustée, même avec un gant épais.

zip double curseur

S'ouvre par le haut ou par le bas selon le mouvement recherché, pour aérer sans tout ouvrir d'un coup.

serrage taille

Se resserre à la ceinture pour couper les entrées d'air froid, même en plein vent de face soutenu.

velcro poignets

Se règle au niveau du bras d'une main, même avec des gants épais sur les doigts par grand froid.

PERFORMANCES

Sympatex membrane, 20,000 mm, RET < 13, recycled polyester

The membrane in our mountain jackets, in a 3/4-length cut for everyday wear

A city jacket has no reason to be less protective than a mountain jacket. The GRAND TETRAS therefore uses the same construction as our technical jackets: an outer fabric, a Sympatex membrane and a lining, bonded together into a single composite. It withstands a 20,000 mm water column, meaning the water pressure it can withstand before letting a drop through, and its RET below 13 lets vapor escape when you pick up the pace to catch a train. All seams are sealed with heat-bonded tape. There's another thing we care about in a jacket worn every day: its color. The fabric passes a test involving 500 hours of exposure to light equivalent to sunlight, and a color that lasts means a jacket you can keep for longer.

YKK Aquaguard zippers, waterproof coating

Waterproof closures, because water always finds the weak point

On a waterproof jacket, the zipper is the most exposed weak link: a simple row of teeth won’t keep anything out. That’s why the pockets on the GRAND TETRAS are fitted with 3 mm YKK Aquaguard zippers, whose matte coated tape covers the teeth and keeps water from seeping in. You can feel the difference: they glide a little less smoothly than a regular zipper. That’s normal—it’s the price of waterproofing. The main zipper uses the same design in 5 mm, with a two-way slider that lets you unzip from the bottom when sitting down or walking quickly. A zippered inner pocket keeps your phone dry, and the large hood adjusts at three points to follow your head movements without blocking your view.

GRAND TETRAS, the third layer of the Lagoped system

Did you know? The rock ptarmigan, our totem animal, changes its plumage with the seasons: white in winter to blend into the snow, it fluffs up its feathers to trap warm air when the temperature drops. It adjusts its protection constantly, never wearing more than necessary.

GRAND TETRAS follows the same logic: it’s an outer layer, the third layer, which keeps out rain, snow, and wind without trapping the heat generated during exertion. It’s worn over an insulating mid-layer, such as a fleece or lightweight down jacket, which itself sits over a technical base layer next to the skin. Put it on when the weather turns, and pack it away when it clears.

Fit & support

Regular fit and 3/4 length: a jacket that layers without getting in the way

GRAND TETRAS comes in a regular fit, a men’s cut that’s neither slim nor loose, leaving room for a fleece or lightweight down jacket underneath without looking baggy around the torso when worn on its own.

The 3/4 length falls below the hips: it protects your lower back when you lean over your pack or sit on a damp rock, and works with a harness as long as the belay loop remains accessible. Your arms have full range of motion when reaching overhead, ice axe in hand or during easy climbing, without the jacket riding up to your waist.

Coupe Regular

Coupe intermédiaire à travers le buste, avec assez d'aisance pour superposer une couche technique en dessous sans compression. Les manches gardent une bonne liberté de mouvement pour les activités outdoor du quotidien, de la randonnée aux sorties en montagne.
