Mero Mero · Wanaka Backpack
A day in 10 litres, with the jacket as well in 15.
It rolls up to hold the day, unrolls for the jacket and lunch. The 3D mesh back stays ventilated when you walk, and nothing sticks out on the outside.

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 Japanese 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
- A light 10 to 15 litre bag, with a ventilated back and the laptop kept safe, that you forget once it is on your back.
- Worth knowing
- It does not fix to the bike: no Velcro straps, no luggage rack, that is the Annecy.
- Who it's for
- For those who walk, take the train or push a child, and want 10 to 15 litres and nothing more.
