Alpine Fit is an outdoor performance gear and apparel company based in Alaska. They assemble close to everything in the US, but not all their raw materials are sourced domestically. We spoke to their team, and they gave us a breakdown of their sourcing footprint. 50% of their raw materials are sourced from US companies. The main domestically sourced material is their fabric, which they call sterling and is actually milled in the US. The following biggest country is Vietnam at ~40% – this is exclusively their wool. They use a supplier based in Canada for the remaining raw material (~10%).
