Mero Mero · Piha Handlebar Bag

Handlebars, waist or crossbody: the 3 to 6 litre bum bag.

It follows the route: strapped to the handlebars for gravel or city riding, at the waist for hiking, mountain biking or cross-country skiing, crossbody once you are on foot. The roll-top sets the volume from 3 to 6 litres, and the mesh back panel stays ventilated against your back.

Mero Mero

Mero Mero, from Annecy to Vietnam.

Born in Annecy

Mero Mero is a French brand, born between lake and mountains. Its first bag, a messenger bag, was inspired by two children, Clémence and Léon. The brand is a member of 1% for the Planet and gives 1% of its turnover to environmental organisations.

Sewn in Vietnam

Since late 2018, manufacturing has been in Vietnam, with a partner specialised in technical stitching: paragliding canopies, harnesses, backpacks. The factory is ISO 9001 and ISO 14001 certified and passes the WRAP audit every year.

Repaired in France

The brand plans for repair from the design stage and works with workshops in France, in Annecy and Lyon.

Eiken's take

Why we chose it: It changes position without being emptied: handlebars for riding, waist for walking, shoulder for the city, with the same roll-top and the same pockets.
Worth knowing: It does not go beyond 6 litres: the essentials for an outing, not a bag for the whole day.
Who it's for: Gravel and city cyclists, light hikers, and anyone who wants a bum bag that doubles as a handlebar bag.

Baptiste, Eiken
