Meet Mainio

“We root for all kids: the explorers, the misfits, the brave ones and the poets. We believe in adventures, field trips, never-ending curiosity and letting kids be kids.”

Mainio champions a better future. The idea from the brand's very beginning was to choose ethical and ecological materials and to only work with partners who take responsibility for the wellbeing of their employees and our planet. That vision became Mainio's core, a value that we still embrace. We know our partners like the backs of our hands and will always stand for openness, transparency and togetherness.
