Hermès Hac à Dos
The Hac à Dos is a Hermès backpack that can also be worn over the shoulder or across the body. The online store lists the Hac à Dos PM, 18 × 28 × 8 cm, at £8,510 in Togo calfskin or £7,630 in Woolycot canvas with Swift calfskin in the UK.
What is the Hermès Hac à Dos
The Hac à Dos is the Hermès backpack, and its name plays on sac à dos, the French word for backpack. Hermès lists the PM with a large main compartment, an interior back pocket, a D-ring and one adjustable strap. That single strap is what makes it versatile: the same bag is worn on the back, over one shoulder or across the body.
Two versions of the PM appear on hermes.com. One is in Togo calfskin, a matt, drummed leather with visible veins. The other combines Woolycot canvas with Swift calfskin and has a plain Wooly canvas strap and a flat interior back pocket. Both versions share the same size and strap length. Palladium plated hardware is the only finish in our reference data.
Hac à Dos sizes
| Model | Dimensions, cm | Dimensions, inches | Strap | What fits |

Hac à Dos PM
The Hac à Dos PM measures 18 × 28 × 8 cm, so it is 10 cm taller than it is wide. Its strap adjusts from 69 to 125 cm, a range that covers both shoulder and crossbody wear as well as the backpack position. At 18 cm wide it takes a phone, a wallet and a small pouch stacked upright, but not a laptop or an A4 folder.
A larger Hac à Dos GM has also appeared in the Hermès online store, though far less often than the PM. We have no Hermès measurements or price for it yet, so it is not in the tables on this page.

How to buy a Hac à Dos
Online at hermes.com
The Hac à Dos is sold through the Hermès online store, mostly as the PM. When we opened the PM product pages on 17 September 2026, every listing showed as out of stock, so buying online depends on catching a restock as it goes live.
In a Hermès boutique
Boutiques hold their own stock, independent of the website. A sales associate can check for a Hac à Dos in store; Hermès publishes no rule on how bags are offered, and buyers commonly report that it varies by store.
On the resale market
Pre-owned Hac à Dos backpacks are sold on resale platforms, often above retail. Buy only from sellers who authenticate the bag, and check whether a listing is the PM or the GM before comparing prices.
