Fit Notes


Sewn In California

Sewn in our home state, the California Collection takes its name from where it’s made. Its domestic production creates jobs, keeps money in the community, reduces the environmental impact of shipping and brings us closer to the process in every way. It’s more than the tangible benefits, though, that make the difference. The “Sewn in California” tag tells a story, and it’s one we’re proud of.
