Description

ISACK Cognac — Warm leather, rigorous design

In its Cognac version, the ISACK briefcase takes on a different presence: a natural, warm tone that catches the light and evolves over time.

The front and back panels are crafted in smooth cognac leather, with a clean finish and a supple, structured feel. The sides, in grained cognac leather, add texture and reinforce the areas that face the most wear. Together, these two leathers create a subtle balance between elegance and durability.

As the years pass, the colour deepens and develops a rich patina. Cognac is alive — it records days on the move, repeated gestures, everyday use. Each bag becomes uniquely yours.

A compact format, intelligently organised

ISACK Cognac keeps a compact, structured silhouette designed to support busy days without adding bulk.

Despite its streamlined size, it fits 13" to 16" laptops. The Alcantara interior, soft yet hard-wearing, keeps essentials neatly organised: laptop, documents, notebook, charger. Everything falls into place, effortlessly.

Details made to last

Brass hardware complements the warmth of Cognac and develops its own patina over time. Protective base feet help preserve the leather when the bag is set down, keeping its structure intact.

Carry it by hand or wear it on the shoulder

Delivered with an included shoulder strap, ISACK Cognac can be carried by hand for a sharper look, or worn crossbody for more freedom throughout the day.

Compact. Functional. Elegant.
Leather that grows more beautiful with time — an object made to last.

    A rigorous selection of full-grain leathers

    Smooth leather

    This full-grain leather has been tanned using vegetable-based products. The finish of this leather is therefore very natural. It has a smooth, matte appearance and will develop a beautiful patina over time. This leather requires minimal maintenance to ensure a very long life

    Grained Leather

    The main characteristic of this leather is its suppleness. It has a matte, natural appearance and will develop a patina over time thanks to its organic tanning process.

    Saffiano Leather

    This full-grain leather has a satin finish that gives it a slight sheen. Its surface coating makes it particularly resistant to everyday wear and tear. This leather requires very little maintenance.

    Metal accessories

    Most of our metal accessories are made of brass. This metal offers excellent strength and corrosion resistance. These characteristics are essential, particularly for carabiners and ground nails.

    Water-repellent cotton fabric

    This twill-woven cotton fabric is very elegant and pairs beautifully with our smooth leather. It has been treated to be water-repellent, making it resistant to stains and splashes: water runs off the surface without penetrating.
