About Koinonia Adventures

Last updated: August 2026

Koinonia is an old word for fellowship.

Specifically, the kind that forms between people who have shared a long trail — the friend who takes the heavier pack without mentioning it, the stranger at the pass who gives you their last water report. We named the company after that, because it's what the gear is for. Clothing doesn't summit anything. People do, together, and their gear either helps or it doesn't.

Designed in Eagle, Idaho

We work out of Eagle, on the edge of some of the best testing terrain in the Lower 48. Every piece in the catalog logs real miles in the Sawtooths before it earns a product page — squall-season shells, shoulder-season insulation, pants dragged over enough granite to find the weak seams. If a prototype fails, it goes back to the table, not into the catalog.

What we hold ourselves to

PFC-free DWR on every treated fabric — the mountains don't need our chemistry outliving us. Seams guaranteed for the life of the garment: if our stitching fails, we repair or replace it, no time limit. And a small line on purpose — twenty-four pieces we can stand behind beats two hundred we can't. Anything else is covered by our 30-day returns.
