Singaporeans are known for being pragmatic — which makes our fascination with the Hermès Birkin all the more puzzling. Designed for another era, it never came with a shoulder strap — except the one made for Jane Birkin. So why are the rest of us still juggling one, especially when nature calls?

When Hermès showed a Birkin harness forFall 2023 but never released it, I took matters into my own hands. HAC À SAC is my answer:a premium “diaper bag” that babysits your Birkin, crafted from vintage Ardennes leather. Named after the Haut à Courroies (HAC),it’s a small hack for Birkin parents who want their hands back.
