From the brand

ADVENTURE ANYWHERE.

ADVENTURE FOR ANYONE.

ADVENTURE FOREVER.

This is the pledge we’ve committed to, and the words we stand for. Since the very beginning (now more than 20 years ago), our goal has been to build a lasting and iconic brand that inspires love for adventure, each other, and our planet, and as a result, everything we do is rooted in three things:

INNOVATION | COMMUNITY | SUSTAINABILITY

INNOVATION

We believe that meaningful adventures are out there for anyone with the will, the imagination, and the right gear.

COMMUNITY

Adventure gives us purpose and perspective. It inspires us to be our best selves — humans who are conscious, connected, and mindful.

SUSTAINABILITY

NEMO is dedicated to inspiring outdoor adventure, and that includes protecting the people and places that make it possible.
