The Hermès HAC 40 Cosmos Bag is a rare limited edition masterpiece.
It displays a hand-sprayed ombré gradient in Blue Nuit, Jaune de Naples, and Aqua.
Because of this artisanal technique, each Cosmos reveals a different balance of color.
As a result, the bag stands as a true Hermès collector’s piece with undeniable visual impact.
Exquisite Craftsmanship
Crafted in richly saturated Togo leather, the HAC Cosmos shows depth, texture, and structure.
Brushed palladium hardware adds a cool, elegant contrast to the vibrant palette.
In addition, this example includes a NON MATCHING lock, keys, and clochette, as the originals are no longer present.
The bag also comes with its Hermès sleeper.
Although preowned, the piece remains in superb condition, which reflects both careful handling and the durability of Hermès craftsmanship.
Heritage and Design
The HAC, known as the Haut à Courroies, dates back to the 1800s as Hermès’ original travel bag.
It later inspired the iconic Birkin while retaining its own distinctive proportions.
The HAC offers a taller profile, narrower shape, and shorter handles, making it highly practical for travel.
Most HAC styles appear in 40 cm and larger sizes, which suits their classic function and strong visual presence.
Although rare, a few 32 cm HAC-styled Birkins exist and follow the same architectural aesthetic.
Collector’s Appeal
Because of its dramatic ombré coloration and limited production, the Hermès HAC 40 Cosmos ranks among the most desirable Hermès travel bags.
It blends history, artistry, and rarity in a way that few luxury pieces can match.
Mightychic proudly presents this preowned Hermès HAC 40 Cosmos Bag, curated with over twenty-two years of trusted expertise in authentic Hermès collectibles.
This Cosmos does not include the original lock and clochette.
The replacement set shown is included, and the bag is sold as is.

The Hermès Cosmos collection is celebrated for its hand-sprayed ombré technique, which ensures that no two bags are exactly alike.
Moreover, each piece reflects the Maison’s experimental artistry while remaining rooted in classic form.
The HAC silhouette provides a large, uninterrupted canvas, allowing the color gradients to flow organically across the leather.
In addition, Togo leather absorbs pigment beautifully, enhancing depth and saturation.
Because Hermès produces Cosmos bags in extremely limited quantities, collectors regard them as standout artistic statements within modern Hermès history.
