Before there was a Birkin, there was the Haut à Courroies. Sotheby’s calls it “the original Birkin bag,” and that is not marketing — the HAC came first, in the 1890s, and the Birkin was adapted from it nearly a century later. For a serious buyer, the HAC occupies a rare position: it carries more heritage than almost anything Hermès makes, it is produced in far smaller numbers than the Birkin, and — crucially — it plays by different buying rules. This guide is the complete picture: sizes and exact dimensions, leathers, hardware, real 2026 pricing, how allocation actually works, authentication, care, and whether it holds value.
What is a Hermès HAC?
Haut à Courroies is French for “high with straps” (pronounced roughly oh-ah-koor-WAH). Hermès was founded in 1837 as a harness and saddle maker, and the HAC — created in the 1890s — was built to carry a rider’s saddle and boots. The two long straps that buckle across the front, and the tall, upright body, are functional inheritances from that purpose. When Hermès adapted the design into a softer, wider everyday bag for Jane Birkin in 1984, the Birkin was born. The HAC is, quite literally, the Birkin’s ancestor — and it has never lost its structured, architectural character. Read the full history of the Haut à Courroies.
HAC vs Birkin: the difference, to scale
The defining difference is proportion. A HAC and a Birkin of the same number share the same width, but the HAC is dramatically taller and slightly deeper. A Birkin 40 measures about 40 × 30 × 21 cm (W×H×D); a HAC 40 keeps the 40 cm width but stands roughly 34–40 cm tall and about 23 cm deep.
Two consequences follow: HAC handles are shorter (hand-carry, like luggage), and a HAC is heavier than the equivalent Birkin because there is simply more bag. See the full HAC vs Birkin comparison.
HAC sizes and dimensions
Hermès publishes no official spec sheet; these are the widely-referenced measurements (width × height × depth).
| Model | Approx. dimensions | Character & status |
|---|---|---|
| HAC 32 | ~32 × 27 × 16.5 cm | The most wearable HAC — discontinued, resale only |
| HAC 40 | ~40 × 34–40 × 23 cm | The classic HAC; taller than a Birkin 40 |
| HAC 50 | ~49.5 × 43 × 27 cm | A genuine weekender / travel bag |
| HAC à Dos PM / GM | Backpack (unpublished) | The rare HAC backpack, two sizes |
Each size has a dedicated guide: HAC 32, HAC 40, HAC 50, and HAC à Dos PM vs GM.
Leathers: what the HAC actually comes in
The HAC uses the same leather library as the rest of the house, but the tall, structured body favours leathers that hold their shape. In practice you will most often see:
- Togo — fine-grained, durable, matte; the most common and most forgiving. The safe default. See our Togo guide.
- Clémence — softer and heavier, with a gentle slouch; frequently chosen for the 40 because it holds the height without stiffness.
- Epsom — firm, embossed, lightweight; the crispest, most architectural look. See our Epsom guide.
- Box calf — smooth, classic, ages to a patina; more delicate.
- Exotics — the Porosus crocodile HAC is a collector-only tier; a large HAC needs far more skin than a small bag, which is part of why exotic HACs are so rare and costly.

Hardware, colours and special orders
Hardware is typically palladium (silver-tone) or gold, with the signature two-strap-and-buckle closure and a turn-lock; on travel sizes it is substantial, reflecting the luggage origins. Colours span the full Hermès spectrum, from neutrals (Black, Etoupe, Gold/tan) to seasonal brights. For established clients, Hermès offers special orders (sometimes called HSS) that allow customising leather, colour, hardware, stitching and interior — the most personal way to own a HAC, and reserved for strong client relationships.
How much does a HAC cost?
Hermès pricing is opaque and rises regularly (a January 2026 increase pushed most bags up several percent). To anchor expectations, current 2026 US retail on Birkins runs about $13,500 for a Birkin 25 in Togo, $14,900 for a 30, and $16,300 for a 35; the HAC à Dos PM in Togo sits around $11,300. A standard leather HAC 40 generally sits in the upper Birkin range and above, given its size; exotic HACs (crocodile) run into the tens of thousands and are effectively made-to-order. Because HACs are frequently produced to order and appear infrequently in boutiques, much real-world buying happens on the secondary market, where price is set by demand. For a full breakdown see our HAC and Birkin price guide.
How to buy a HAC: the quota-bag reality
This is where the HAC genuinely differs from the Birkin, and where most buyers get tripped up. The Birkin and Kelly are quota bags: Hermès limits each client to a small number per year (commonly understood as roughly two, one every six months), and they are allocated only to clients with a purchase history the boutique values. The HAC is generally non-quota — still scarce and still allocated at the discretion of your sales associate, but not bound by that same hard ceiling.
In practice, buying a HAC new means:
- A relationship with a sales associate (SA). Allocation follows purchase history and rapport, not a public waitlist you can join online.
- Time. Waiting for a specific size, leather and colour can take months to years; the most exclusive configurations (exotics, rare colours, special hardware) go to top clients.
- Flexibility helps. Being open on colour or leather dramatically shortens the wait.
If you do not have an established boutique relationship, the realistic route is a reputable authenticated reseller, where you can buy a specific HAC outright today — see where to buy authentic pre-owned Hermès.
Buying pre-owned and avoiding fakes
Because HACs are rare and expensive, they are a frequent counterfeit target, and large exotic examples especially so. Protect yourself with two rules: buy from sellers that authenticate every item (or from Hermès), and learn to read the bag — the date stamp, the evenness of the hand saddle-stitching, the weight and engraving of the hardware, and the leather grain. Our authentication guide and date stamp chart walk through each signal. A “HAC” priced far below market with no provenance should be treated as fake until proven otherwise.
Caring for your HAC
A HAC is an investment, and leather is sensitive to water, oil, heat and light. To keep it pristine:
- Keep it dry. Water is the enemy — avoid rain, drinks, hand sanitiser and pens. Hermès historically tucked a clear raincoat inside its bags (through 2024); keep one (or even a plain plastic cover) with the bag. If it does get wet, wipe immediately with a soft, lint-free cloth to prevent stains and blisters.
- Store it properly. Keep it in its dust bag and box, stuffed with acid-free tissue to hold the shape, away from direct sunlight, humidity and heat.
- Do not hang it — that distorts the structure over time.
- Rotate use and wipe the exterior with a soft, slightly damp cloth to lift dust; use only leather cleaners made for fine leather goods.
Does a HAC hold its value?
Hermès leads all luxury brands on resale, retaining around 138% of retail on average per recent market data, and rarer pieces in desirable specs can do better still. A HAC’s rarity works in its favour, though large and exotic examples serve a narrower collector market, which can affect liquidity. See our resale value analysis.
Who should buy a HAC?
The HAC suits the buyer who wants something rarer and more storied than a Birkin, likes the tall, structured, top-handle character, and either has a boutique relationship or is happy to buy authenticated pre-owned. Choose the 32 or 40 to actually wear it, the 50 for travel. If you want maximum versatility and availability instead, a Birkin may serve you better — compare in HAC vs Birkin.
Frequently asked questions
Is a HAC bigger than a Birkin?
For the same number, yes. A HAC shares the Birkin’s width but is significantly taller and a little deeper, so it carries more and looks larger overall.
Is the HAC a quota bag?
Generally no. Unlike the Birkin and Kelly (quota bags, limited per client per year), most HACs are non-quota — still scarce and allocated by your sales associate, but not bound by the same hard limit.
How much does a HAC cost?
It varies by size, leather and hardware and is often made-to-order. As an anchor, 2026 US Birkin retail runs roughly $13,500 (25) to $16,300 (35), and the HAC à Dos PM about $11,300; a standard HAC 40 sits higher given its size, and exotic HACs reach into the tens of thousands.
What leathers does the HAC come in?
Most commonly Togo and Clémence, also Epsom and box calf, plus exotics like Porosus crocodile for collectors.
Is the HAC hard to buy new?
Yes. It requires a boutique/SA relationship and often a wait of months to years for a specific spec. Authenticated resellers are the faster route to a specific bag.
How do I care for a HAC?
Keep it dry (water is the main risk), store it stuffed in its dust bag and box away from sun and humidity, never hang it, and wipe gently with a soft damp cloth.
Is the HAC older than the Birkin?
Yes. The HAC dates to the 1890s; the Birkin was introduced in 1984 and was adapted from it.
Do HACs hold their value?
Yes — Hermès leads luxury resale (around 138% of retail on average), and the HAC’s rarity helps, though very large or exotic pieces serve a narrower market.
