Description

Depth and precision

In Brown, the ISACK briefcase takes on a richer, more architectural presence. A deep, nuanced shade that brings together classic elegance and a distinctly contemporary feel.

The front and back panels in smooth brown leather have an even, almost satin finish that defines the silhouette. The grained brown leather sides add texture and durability, reinforcing the areas subject to everyday movement and wear. The pairing creates a subtle contrast between clean surfaces and pronounced texture, each balancing the other.

The result is understated, with a character of its own.

A compact format designed for efficiency

ISACK in Brown maintains a streamlined profile, ideal for busy days. It accommodates 13- to 16-inch laptops while retaining a compact, defined silhouette.

Inside, the soft, durable Alcantara lining surrounds your essentials: laptop, files, notebook, and charger. Thoughtful organization gives everything its place.

Considered finishes

Brass hardware complements the depth of the brown leather, adding warmth and a subtle architectural accent. Protective feet help shield the leather when the bag is set down, preserving its appearance over time.

Carry by hand or over your shoulder

Complete with a shoulder strap, ISACK in Brown can be carried by hand for a structured look or worn over the shoulder for greater freedom of movement.

Rich. Precise. Contemporary.
A work essential built 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 rock 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.
