Hermès HAC à Dos Backpack: PM vs GM, Sizes & Prices

HAC à Dos Sizes: PM vs GM vs Maxi

The GM is 8 cm wider and 8 cm taller than the PM, which gives documents and a tablet more room. The Maxi is wider and deeper again, and has a pocket designed for a laptop. Hermès gives the dimensions below as approximate because the bags are handmade.

The bag measurements are width × height × depth. Strap length is the full adjustable length, so it is not the same measurement as shoulder drop. The PM strap extends about 10 cm farther than the GM strap; a bigger bag does not automatically have a longer strap.

HAC à Dos PM: a compact daily bag

At 18 cm wide, the PM works more like a small crossbody than a conventional backpack. A phone, compact wallet, keys and sunglasses suit its narrow body. In a PM and GM owner comparison, travelguy2500 describes packing an umbrella, sunglasses and a small toiletry case in the PM, but finding it too small for their iPad. Those small items suit a day out; a tablet or computer calls for a bigger size.

HAC à Dos GM: more room, one strap

The GM adds 8 cm of width, 8 cm of height and 3 cm of depth. It has room for a tablet, papers and more daily belongings; the same owner comparison describes carrying a laptop and cords in the GM, without naming the computer. Hermès does not call its back pocket a laptop compartment, so the outer measurements alone cannot guarantee that a particular computer and sleeve will fit.

HAC à Dos Maxi: the laptop pocket

The Maxi measures 32 × 43 × 15 cm and adds an interior laptop pocket plus a removable zipped pouch. That makes it the clearest choice in this family for carrying a computer, though Hermès does not publish the pocket dimensions or a supported screen size. It also carries its larger load on one strap.

Hermès HAC à Dos Prices in 2026

Standard U.S. PM versions remain $11,300 in the latest listings, while a Togo GM is $13,200. The PM Haccess is $16,600, so its extra pockets add $5,300 over the standard Togo PM. The dates below show when each price was recorded; the Barenia GM and Maxi have older records than the other versions.

Material and construction change the price even within one size. H canvas/Togo GM costs $200 less than the all-Togo GM; Barenia Faubourg costs more in both PM and GM. The standard PM is the least expensive of these recent U.S. examples.

HAC à Dos resale prices: current asking prices

On October 3, 2026, five live Fashionphile PM listings in Togo or Swift, all described as Excellent, asked $8,725–$10,595. That puts these particular bags below the $11,300 retail price. Two recent Rebag Togo PM listings asked $13,655 and $13,910, showing why it pays to compare the exact leather, color, condition and accessories before buying.

Those are seller asking prices, and a listing becoming unavailable does not prove a completed sale at that price. Buy the HAC à Dos because you want to use it; this small group of offers does not support a guaranteed return when you resell.

Materials, Pockets and Carry

Togo has a matt surface with a rounded, irregular grain and becomes softer over time. Swift is almost smooth, lightly glossy and very supple. Barenia Faubourg feels waxy and velvety, and develops a darker patina where it is exposed or handled. Canvas-and-leather versions keep the same basic body shape but add a different texture.

Standard PM and GM versions have a large main compartment, an interior back pocket and a D-ring. Haccess adds separate phone and card storage, while the Maxi has its laptop pocket and removable zipped pouch.

All three sizes use one adjustable shoulder strap. You can move the bag from your back to your side or front, but the load still hangs from one shoulder. Wearers comparing PM and GM disagree on which looks and feels better on them, so there is no useful height cutoff that makes one size right for everyone. For a heavy computer-and-bottle load, a backpack with two straps distributes the weight across both shoulders.

HAC à Dos Haccess: extra pockets in PM and GM

Haccess adds raised front storage to the PM and GM without changing their basic size. Both versions have a removable pocket for one or two phones, card storage behind the flap and two interior card slots. The GM adds a smaller pocket for a cardholder or other small items. The front pocket keeps those small belongings separate from the main compartment.

A U.S. Togo PM Haccess was $16,600 on September 8, 2026. A France GM Haccess was €14,800 on September 25. The French figure is for that market; it does not establish a U.S. GM Haccess price.

Haut à Courroies Multipockets is a different model: a version of the larger travel bag with layered exterior pockets. Haccess is the name to look for when you want the HAC à Dos backpack with extra phone and card storage.

HAC à Dos Dupes and Branded Alternatives

A search for a HAC à Dos dupe often starts with the same practical need: a backpack or sling bag you can carry hands-free. A different branded backpack can meet that need while using its own shape, closure and strap arrangement.

The Hermès Bolide à Dos has a zip opening and rounded body, the Goyard Alpin Mini is a compact canvas backpack, and the Louis Vuitton Montsouris PM uses a more conventional backpack shape. The HAC à Dos alternatives guide compares their dimensions, carry methods and buying options.
