Frequently Asked Questions
TreeSilk™ is One Golden Thread's proprietary fabric — a blend of European Beechtree fiber and the top 1% of ethical cotton. It's ultra-soft, stretchable, and breathable, with a "second skin" feel in Jersey weight and a plush, cashmere-like hand in French Terry. The reversible French Terry version even offers a built-in temperature swing: wear the fuzzy side in for warmth, or flip to the smooth side to stay cool.
TreeSilk™ comes in four varieties: RAW (ultra-fine, fluid, and cooling), Jersey (the signature "second skin" feel), Fleece (soft, steady, and thermodynamically calm — that's the reversible French Terry with the 15° warm/cool flip), and Linen (a breathable blend of European Flax® linen, beech tree fiber, and California cotton for structured, elevated ease).
Pieces are ethically handmade with fair wages in LA and Mexico. You can also shop in person at the brand's flagship store at 1216 Abbot Kinney Blvd., Venice, CA, open daily 11am–7pm.
