global coordinates

The numbers on these masks are the global coordinates of the the Limahuli Garden and Preserve in the Kauai, Hawaii — a reminder that we’re all connected no matter our gender, race, religion, or where we live.

Limahuli Valley is home to archaeological complexes, native forest, pristine stream, dozens of endangered plants and birds found no where else on earth, and the descendants of the valley’s original inhabitants. The Limahuli Garden and Preserve is a uniquely Hawaiian place of refuge and honors ancestral traditions by continuing indigenous practices to address modern conservation challenges and restore health, function, and resilience to the valley.

Comfortable, Breathable Masks

Keeping these masks on hand for travel. They are the most comfortable. Non-slip, use multiple times and love the now biodegradable option.
