Gear for theLong Way Around

Shells that earn their pack weight, insulation that works when damp, and pants cut for the high step — designed in Eagle, Idaho, and trail-tested in the Sawtooths before anything ships.

Koinonia — an old word for fellowship

The Company We Named After the Trail Itself

It describes the kind of fellowship that forms between people who've shared a long trail — the friend who quietly takes the heavier pack, the stranger at the pass who hands over their last water report. Clothing doesn't get anyone to the summit; the people wearing it do. Ours just has to hold up its end.

We work out of Eagle, Idaho, on the edge of the Sawtooths, and every piece in the catalog logs real trail miles there before it earns a product page.

What You're Actually Paying For

Fewer Pieces, Held to a Higher Bar

Trail-Tested Before It's Catalog-Ready

Every piece logs real miles in the Sawtooths — squall-season shells, shoulder-season insulation, pants dragged over enough granite to find the weak seams — before it earns a product page.

PFC-Free, Full Stop

Every treated fabric in the line runs PFC-free DWR — the mountains don't need our chemistry outliving us.

24 Pieces, Not 200

A small line on purpose — twenty-four pieces the team can stand behind, from shells to headwear, beats two hundred it can't.

Ember Creek Heavyweight Flannel

Spotlight

Ember Creek Heavyweight Flannel

A proper camp flannel: heavyweight brushed twill with real heft, not the tissue-paper kind that pills by Thanksgiving. Triple-needle seams take firewood duty, the chest pockets button shut over a phone, and the tails are cut long to stay tucked when you lean over the tailgate. Gets softer every wash and better every trip. Wear it open over a tee until the stars come out.

From the Workbench

“Clothing doesn't summit anything. People do — and their gear either helps or it doesn't.”

That's why every treated fabric in the line runs PFC-free DWR, why seams are guaranteed for the life of the garment — repaired or replaced, no time limit — and why nothing ships until it's logged real miles in the Sawtooths first.

Before It's In Your Pack

What People Ask Before They Buy

What's the difference between the Ridgeline 2.5L shell and the Sawtooth 3L shell?

The Ridgeline is a 2.5-layer 40D ripstop that packs into its own chest pocket — the one to grab when weight matters. The Sawtooth steps up to a 3-layer 70D build with a tricot backer and a wire-brimmed hood, built for the days you'd rather not tell your family about.

How do I keep the PFC-free DWR finish working?

Wash cold, tumble low, and re-treat the DWR when water stops beading on the face fabric — heat from a warm dryer cycle also helps revive it between treatments.

Can the merino base layer handle multiple days without a wash?

Yes — the Meridian Merino Blend Crew is built for that. The merino-nylon blend keeps wool's odor control and warmth-when-damp while the nylon core holds up to pack straps over repeat wears.

Where is Koinonia gear actually designed and tested?

In Eagle, Idaho, on the edge of the Sawtooths. Every piece logs real trail miles there before it earns a product page — if a prototype fails, it goes back to the table, not into the catalog.

Why does the catalog only have two dozen pieces?

On purpose. Twenty-four pieces the team can stand behind beats two hundred it can't — every SKU earns its spot.

Does the daypack work with a hydration bladder or rain cover?

The Divide 24L Daypack is hydration-compatible with a dedicated rain-cover pocket built into the lid, plus a stretch front pocket for a shed layer.
